Spontaneous zoom auto/output problem

In almost ALL applications (MS Word, Notepad, Wordpad, Ezplorer Internet, MSN chat window, MS Paint, etc.) in the window where text or graphic is displayed and can be enlarged or back, or the user can change the font sizes, sometimes I encounter the phenomenon when the mouse cursor is moved in the window, the size espontaneously display is zoomed in to the maximum (~ 800%/96pt) OR minimum (~ 10%/6pt). It occurred just before my submit this question: in Word2007 (he used to do that too in 2003), the text expanded to the maximum, while at the same time in IE8 (used to do also in IE7) the display zooms in to min.

Close the application and reopen it do not negate the phenomenon, once it starts. I tried to determine if it is caused by a background application, without sccess. Also logging out the user (there are 4 defined users on this PC) and reconsignation in won't stop him.

The way only I found to stop this phenomenon, once it starts, is to restart the PC.

Your help to identify the cause of this problem and to make changes to prevent it will be appreciated.

Yours sincerely,

Hylton

I accidentally discovered the cause of my problem a few days ago.

You were correct that it's a hardware problem, not software, but in my case, it is NOT my mouse. This is myKEYBOARD.

I have a Microsoft keyboard that has a small sign on the left with failover application, cut/copy/paste and traction rear buttons and a scroll wheel. This section has the problem. I normally do not use them since I was mostly the same features on my mouse. If the problem occurs and I give these buttons light a few "shots", the problem disappears (until the next time, which is rare).

My keyboard is now also show other signs of age (he has ~ 5 years): some keys are sometimes not the first time they are activated and sometimes also need to be pressed very firmly before operating correctly.

Maybe I need a new keyboard... or I could try to deliver it - I like it a lot, and I saw others like him to sell today:-)

  • Zoom r16 output does not reflect the master Pro Logic output

    I have a Zoom R16 hooked to Logic Pro X on El captain.

    Everything seems to work fine, but the release of the Zoom R16 always gives the sound, the monitor of the line, not the output of Logic Pro X inputs. If the helmet and out of line always give the full release of all entries and not the combination of Logic Pro. On the master output indicators seem to give the right indication (that is, not if all the sliders are declining), but that does not reflect the sound on the output.

    Is this a settings problem, a problem with Logic Pro or a problem with the Zoom R16.

    Anyone who suffers it, or has a sollution?

    How exactly this is connected to your Mac?  I guess that via USB?

    You have the latest drivers for it?

    Have you checked the Audio 'MIDI settings' application (Applications > utilities) to check that it is correctly configured in the operating system?

    Have you checked its configuration in LPX?  Two place to check.  1 - logic Pro X menu > control surfaces > Preferences 2 - Logic Pro X menu > control surfaces > Setup

  • HDMI output problem with w2207h

    Monitor: w2207h with 3.0.0 (most recent) drivers installed.

    OS: Windows 7

    Computing: Firebird 802, x 2 9800 S with a nForce 760i SLI

    Problem: After upgrading video card drivers I lost output HDMI, no longer gives a signal.

    I am currentnly using a VGA cable with DVI adaptor as a workaround.

    I tried to uninstall the drivers and going back to previous known working more, but now the problem still persists.  Each install properly said, removed the old drivers and made a full stop down. I've uninstalled and reinstalled both monitor and nForce drivers.

    I tried four sets of drivers:

    197.45 (used to work)

    260.99 (used to work and update 197.45)

    266.58 (nvidia recommended).

    267.24 (beta).

    I also left auto-install win7 it's set of drivers with no luck.

    I also tried to Exchange another HDMI cable with the same results.

    Something to note: I can plug in VGA and HDMI at the same time. The monitor uses input VGA although HDMI is the default value. Under control Panel\Appearance and Personalization\Display\Screen resolution - display I see two choices of monitor. If I force it to choose the HDMI selection it works, but as soon as I unplug the cable VGA monitor loses signal and falls asleep.

    I have accumulated my brain for 8 + hrs on it. Any help is appreciated.

    Also, what happened on the HP Voodoo specific forums They have merged?

    Great success!

    Here's how I solved it.

    1 borrowed a second monitor from a friend it connected via VGA. Also connected my monitor via HDMI.

    2 the navigation target Panel\Appearance control and the Personalization\Display\Screen resolution on the VGA monitor.  Changed display image duplicated on both monitors and it WORKED. I was finally viewing HDMI on my monitor main but forced resolution 1280.

    3. under the control panel nvidia-> put in place several tab displays, monitors showed, I deselected the VGA monitor (it's disabled/grayed out until I did a reboot) and this allowed me to take back the HDMI @ my natieve resolution 1680.

  • LabVIEW synthesizer: sound via his MacBook card output problem

    Hi all!

    First time posting here, I hope I'm in the right section of the forum. In any case, I am a part-time student and is currently studying a module on Labview at the University. Like a mini project I decided to build a synth using Labview. I built for the most part, but I'm having a little trouble out of sound for the sound card. I am also having a bit of trouble getting the waveforms to play for a long period of time.

    I was copying sort of the configuration of one of the example of screw (generation sound vi I think) and an another vi I found online, but I can't seem to get mine to work using my synth design. I have two problems, one is that the waveform only play for a very short time, but the main problem is that I am getting an error (error 4803) saying the sound card can not accommodate the specified configuration, but I can see my setup is more or less the same as the generation sound vi (which works on my thin macbook). Obviously I'm missing something, so I decided to come here and ask for help.

    I'm guessing that the type of data connected to my exit the configure vi would be a problem because it has a red dot on the input terminal. Any suggestions on how I should resolve this problem?

    I have my attached vi. Any help would be appreciated!

    See you soon!

    Edit: I have already corrected the error 4803. Had to change configure the entry to the audio output sub vi. Now, I just have to find a way to get the sound to play for more. Any ideas anyone?

    Ok. You have several problems.

    The order of cluster in your cluster size is rate, Bits, channels, while the order in the cluster 'sound format' on Configure.vi of output is the frequency of sampling (s/s), number of channels, bits per sample. LabVIEW connects clusters according to the order of cluster. How to avoid this: Pop up on the conpane format of its terminal on the icon Configure.vi to audio output on the block diagram, and then choose Create a control. This will put a control with the same names and the order of cluster on the front panel. You can change the name if you wish as long as you do not change the order of cluster. The alternate is to unbundle your cluster control data, and then package it to the cluster of entry. I watch this the change of your attached VI.

    The VI does not meet the Stop button until the structure of the event runs, which occurs when a key is pressed. FIX: Add a case of event for the Stop value change event. I watch this the change of your attached VI.

    The VI does not recognize changes in the Octave, Amplitude, Osc Select or filter frequency until the second keypress after changing one of these controls. Why? Stream. These controls are probably read in the microseconds after one iteration of the for loop starts. They do not play again until the next iteration no matter when or how many times they are changed. The loop will not iterate until the end of the structure of the event, which only occurs when a key is pressed. The Fix: Case of event for changes in value on these controls. Note that this does not work because now there is no set frequency. So you have also some registers at offset. Because of the problems mentioned, I did not it in modified VI.

    Then, the structure of the event freezes the façade has not completed the code inside. This becomes very apparent when you set the duration to 2 seconds, press multiple keys quickly. The solution to this issue and the problem in the previous paragraph is a loop parallel archtitecture, such as the design of producer/consumer model.

    Not a problem but another way to do something: use the scale of power of 2 in the digital palette instead of the case connected to Octave structure.  I watch this the change of your attached VI.

    Now to your question on the tone duration: the duration of a signal generated by the sinus Waveform.vi and others is determined by the sampling frequency and the number of samples. You are studying, you can do the math. You need to adjust the number of samples as the sampling frequency is fixed.

    The modified VI works fine on my iMac.

  • Digital output problem

    Well, I thought I had everything figured out, but we have finally had time to go to our lab and test it and there seems to be a problem with the output digital here.  I'll look at what's the point of this VI, then describe the problem

    Analog input is entered and analyzed as digital outpt is sent several lines (3).  The digital output is used to send a single, user‑defined delayed pulse TTL with other instruments like triggers.  I put this program to create an array of digital waveforms for each channel, each of them are of the same length as the analog input.  '1' is inserted in the appropriate place in the table, in lieu of a value of '0', creating the required table.  This table would be written on a digital line (1 channel, samples of N).  Three of these subVIs are used here, so three signals various tables are created and writtin in its respective lines when the program runs, the analog input seems to work very well, but that a single digital output is executed.  I need all three lines to write simultaneously.

    I use a USB-6221 with LabView 8.2

    I have attached all the files needed to run this program, and if the 'LabView programs' folder is saved on the C drive, I think that the paths of the files must be correct.

    Thanks in advance

    Hi Chris,

    Hello and I hope that your well today.

    Thanks for your updates.

    I think that my being better if we start from the beginning.

    1 could you try the example Correlated Dig writing with Counter.vi from the Finder of example of NOR?

    It produces output meter as the time base for the digital output - to get clocked at digital output. Don't you see the waveform being printed on your outings that match the graph of digital waveform on the front panel?

    If not, try to use one of the other examples, as Scripture Dig Port - this is a single VI just to send a single value for each digital line. If this does not work, there is a connection problem.

    2. If we got this far without problems, then the next part would be to change the waveform so that you could write the data that you want to...

    The digital waveforms can be made a boolean table, then using the array of Boolean DWDT to Digital.VI to convert into the type of digital waveforms. The waveform will have X number of samples. Therefore, at each clock pulse, you will produce 1 sample on each channel. So if you set the rate for 1000 and the number of points to 1000 (samples) it will display the waveform on a second. (as his continuous the DAQmx will make a loop through the buffer and start out of the waveform again).

    Note, have you seen the palette of digital waveforms? It is located under waveforms and has more vi like the Boolean DWDT to digital.

    Please let me know how you go.

  • Analog output problem

    I'm working on a project that gets an analog input by thermocouple and using temperature data according to certain criteria, the system will give analog current. The problem is then that gives the result of the daq assistant, only the preference of voltage is available in analog output and the program displays PCI-6036E and two channels of it. Current output Anolog is possible or if I use the output voltage must be to my connection go OR-6036E(it is inside the computer case) or I could use SCXI-1300 as I used to get input?

    The 1102 is only a voltage input module, that is why it does not appear in the DAQ Assistant.  You will need to either straight out of the 6036E or you can buy a module for SCXI analog output as the 1124 or 1581.

  • Pavillion dv7 4177nr: VGA output problem and catalyst control start link

    I don't know if the problems are related or if I made things worse.  It started with an error message on uo start saying that there is a problem with Catalyst Control fail to start.  He always allowed did not work me to function normally until, in front of an audience, the o/p to a projector VGA connection.  I had a spare cable who has not remedied the situation then my class sitting around the laptop.

    Another symptom is that the HDMI output is not working.  I do not ko wif it's a separate issue.

    With the notion that it was connected, I set attemping to remove and re-install the drivers AMD and blindly assumed that it was where I'd get the update of the Cat command.

    I used the AMD compatibility checker and installed for the AMD M880G with ATI Mobility Radeon HD 4250 graphics card.  The driver version is 8.770.2.1000 dated dated 19/09/2010

    I can't duplicate the display or projector only use but when I attach an external monitor laptop change resolution as to accommodate the additional display.

    I only need to check the applicability of the changes that I made, or I need help to plan a way out of the mess I made.

    Hello g_david,

    Thanks for the quick response!

    To eliminate the possibility of a software problem, I have recommended to perform a backup and restore of your operating system. This can be done by following this document on the backup of files (Windows 7), and more to perform a recovery of the system HP (Windows 7). This should return your system to the factory settings.

    If the problem persists, please call our technical support at the 800-474-6836. If you do not live in the United States / Canada region, please click the link below to get help from your region number.

  • TMS 14.3 - auto connect problem - multiple call attempts

    Hi people,

    I have a client with an environment with TMS 14.3, conductor XC 2.2, VCS 7.2.2 TP Server 3.1 and CUCM 8.6.2. They have several items on VCS and several endpoints of CTS/TX registered to CUCM Cisco and Polycom endpoints. There is a trunk SIP between CUCM and VCS. Conductor is integrated with VCS by using the B2BUA deployment model. TP server is behind the driver used as multipoint resource only for conferences scheduled through TMS.

    We are having problems when planning a Conference at TMS using type "Auto-connect" and setting driver to dial a number to the selected participants. For some end points when the meeting starts, conductor made several calls try to participants, even after participants answering the call. For example, conductor connects to an endpoint 3000 CTS, CTS answers the call and connect to the meeting, but a few seconds later, conductor's call another attempt at the endpoint, then endpoint answers the second call and put the first call on hold.

    This problem occurs for the following parameters:

    • Endpoints of Polycom HDX series
    • CUCM items of endpoint CTS/TX
    • Outside dial participants (those selected on the tab 'External' to the planning page)

    The problem does not occur for any endpoint TC registered in VCS.

    As a troubleshooting step, the client was trying to configure TMS to try to connect to the participants once (using the "Attempts to connect for scheduled calls" setting value 1), but the issue still occur.

    Tomorrow, I'll be on the customer's site to check if this strange behavior has been generated by TMS or by the chef himself. I really think that it is some sort of bug. I don't know that their environment has been configured properly according to the Cisco documentation, because I was the person who made the project.

    I'd appreciate any suggestions really.   =)

    Thanks in advance.

    My answer was helpful? Please note the useful answers and do not forget to mark questions resolved as "responded."

    Hi Paulo,

    a few days back we had seen this problem and I filed the bug "CSCui90143."

    Currently, we anticipate that this problem occurs because the MSD is not able to understand the message of feedback from the conductor.

    I hope that clarifies. I don't have to if you want to be able to access the bug or not.

    It's really, really weird.

    Check your version number is 13.7.1

    If this is the case, try to reset your preferences the next time you start AE

    1. Press Ctrl + Alt + Shift while starting the AE.
    2. A dialog box launching asking you if you want to delete your preferences file.
    3. Also restore the shortcut keys by default, Alt + click (Windows).
