Odd spike in the graph of the position when using facilitated easier?
Hello all-
I encounter this problem recently and can't seem to find a solution (TBH don't know exactly how you get it either).
Creating two keyframes for position of a layer, even when the thing is moving in a straight line with no other keyframes, I get this weird effect where the layer of sort of "wanders" out of the way before arriving at its final destination. When I open the graph editor for post curve looks like this:
I want a smooth curve between the two keyframes, or a straight line, but rather boost MI get which is odd. This continues to has and I can not find a coherent reason and its driving me crazy
Thank you very much for your help!
The default spatial interpretation gives the energy of movement. Sometimes when you set or move there is a small delay and you get a little pingpong or unexpected because of the energy in the movement movement when the position is changed by a keyframe. If you zoom in and look in the path, you can see which overlap the Bezier handles on the path. This problem is extremely difficult to fix in the graphics editor by dragging the autour values. When you set the default linear spatial interpretation this energy with all its vectors is removed, so you get straight lines between points. This can work very well for your entertainment, but most of the things I design works best with energy and curves.
If you have a problem like this example and you need to maintain a curve and want to smooth movement, it is generally easier to start in the Composition Panel by examining the path and use the tool (g) feather and modifier keys Alt/Op; ion and Cmnd/Ctrl to set the curve. Take this example:
Correct with the pen tool gives me this:
The other option is to adjust the speed Keyframe or keyframes Interpolation to smooth out the path and movement.
In most cases, if you want a smooth path, then it is better to start with the pen tool in the Composition Panel and then work on schedule. Then you can refine things with the tools of the keyframe. If you need to do a few poles using the graph Editor, it is usually a good idea to have the reference chart (speed in this example) visible and choose Edit Position to the position and the speed of change at the moment.
Because of the energy put into movement along a curved path editing speed or graphics of values can get really confusing. That's why I usually start in the Comp panel.

Strange glitch Visual on the taskbar when using Firefox
Hello
I feel a strange glitch Visual on the taskbar when using firefox.
Please take a look at this short video because it shows the problem, it's almost impossible to show in pictures.
https://DL.dropboxusercontent.com/u/12595174/VIDEO0016.3gp
I use firefox on Windows 7 Pro 64 bit v36.0.1. Video card is an ASUS R9 280 X using the latest drivers from AMD 14.12 Catalyst Omega Software.
Motherboard is an ASUS M5A88 with 16 GB of ram and a processor of 6300 FX.
It is a new construction that I have implemented in the last 24 hours, and this behavior was not present on the system using the same version of windows, firefox and even map chart and drivers. But on another card mother and CPU. Previous Board of Directors has been
M4A79XTD EVO with a Phenom II X 4 955BE.The glitching does not occur when it is on the desktop and firefox is closed. It will not occur when you use IE - 64 nor does it when I am using the steam software or any Explorer windows/opening files.
All the motherboard drivers are installed correctly, the integrated graphics card is disabled in the BIOS. I disabled the settings of firefox for hardware acceleration, smooth scrolling and text... to see if it was the question. It wasn't.
I'd appreciate any help to solve this... Really, I don't want to use a different browser but it's bad enough and quite distracting to really annoy me, and I don't see any alternative.
Thank you very much.
HHi jscher2000
I was about to post a reply, because a friend suggested that maybe that's a rendering of issue rather than a firefox one video card even if it's strange how it affected firefox only. I didn't have a chance to test it on Chrome as it is a new construction and I don't want to install the software, I do not use.
I went to the Manager of catalyst and had a glance to the settings. I changed something, but no help... I then started to make a simple change and test until I found that the activation "gpu up-scaling" in the properties of digital flat screens has solved the problem.
I am now free twinkle
Thanks for your quick response however.

Have you shut down / turning your Mac off... power off the USB drive... Connect the drive to the Mac... start up the Mac... then, turn on the USB drive?
If no help, there are a number of posts to the thread in the forum El Capitan of support from users who have problems on their Mac USB. You can post there to see if anyone has the answers.

Ah, looked carefully at the code, and I think I found the problem.
You call removeChild for BOTH myVideo and myLearn - when the only one of them is on the display list.
The if() statement could catch it, BUT you check if they are null, not if they are on the display list. An object can be non-null and not be on the display list.
The simplest method (also somewhat sloppy method) to get rid of this would be to add a try/catch around two of these calls removeChild.
try {}
removeChild (myVideo);
} catch (e) {}
try {}
removeChild (myLearn);
} catch (e) {}
It's messy, it triggers the error again, but it immediately masks because you caught and did nothing, but the error is no longer displayed.

We have a Mac mini connected to a screen and a projector via HDMI using a HDMI splitter.
It works fine for most applications, but during presentations PowerPoint, presenter is displayed on the monitor and the projector.
When I disconnected the mini Mac's HDMI cable and put it in a MacBook, the presenter appeared on the MacBook screen (as it should) and only the slide appears on the screen and on the projection screen.
Of course if we have to use the MacBook for presentations instead of the Mac mini, you would need to have seen the presenter on both the screen and on the screen of the MacBook.
In the Mac mini display preferences there is no button to "Gather Windows" when the Mac mini is attached to the screen and the projector via HDMI splitter is a tab "setting."
But these two things appear on the MacBook when it is connected.
Any help would be greatly appreciated.
Thank you!

Distortions of the screen when using Firefox on Android
Hi, a recurring problem - when using Firefox on my Android Web site, are often distorted. If I try to zoom before to increase the size of police or image during playback, the screen breaks and distorts, with different sections of text and images disappear (black sections of the screen appear) or overlapping, often in a different font sizes. The Web site displayed on the screen as "jumps around." The same thing happens if I try to select text for copy - it is impossible to select all or selection is distorted. I have not had this problem before and noticed only recently. Almost impossible to use the browser now! What is the result of an automatic update of the software? Help, please! Thank you.
Please try to update to Firefox 38.

How can I fix the redirects when using Firefox 30? Windows 8.1.
I've redirected and/or pop ups using Firefox 30 with Windows 8.1. He started immediately with the download of the said Windows 8.1, so I think it came with this download, and although I have run deep scans and even a pre-start with Avast scan, as well as a scan with IObit Anti Malware, I always get the redirects or pop ups.
A smart redirection (context sensitive) it's trying to get the money from you. For example, I had tried to stop the pop ups [redirects, maybe] with the pop-up blocker probably integrated into Firefox, but Firefox Help leads me to an # 800 who offered to connect remotely and fix my PC with certified technicians as you will see in the chat below. He appeared as a function of Firefox, not a redirect.
Just after the chat with the 800 suit, I opened FireFox and he went to the (default) url: start.mysearchdial.com/ and a hash string more, which is perhaps how popups spreads?
I'm from mozilla via a url and soon encouraged me to download the new version, saying a current obsolete. But he was not going to download it from: http://downloadsoftware.pw/download/firefox2/He isn't very smart, it is also resistant to many software removal tools.
What could suggest you? I tried not many of these tools yet.
MySearchDial must have an entry in the Control Panel, but may also have fangs in your browsers.
Control and cleanup that will take a few precautions. I suggest starting here:
Open the Control Panel, uninstall a program. Click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Out as much garbage as possible here.
Then, in Firefox, open the page modules using either:
- CTRL + SHIFT + a
- "3-bar" menu button (or tools) > Add-ons
In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions.
Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.
Finally, you can "absorb" remain problems with the scanning/cleaning tools listed in our support article: Troubleshooting Firefox problems caused by malware.
Are you able to get rid of him?

Hello captainlarrydart,
Thank you for using communities of Apple Support.
If I understand your message that your Mac is apparently going to sleep on his own, sometimes immediately after waking up. To help solve this problem, please follow the steps below.
If your Mac goes to sleep in an unexpected way
Make sure that this energy saver is set up as you wish: choose the Apple menu > System Preferences, and then click energy saver. Adjust one or more of the following affect when controls your Mac goes to sleep. Some of these controls are not available on your Mac model.
- Cursor 'turn off display after.
- Cursor "display sleep".
- Slider 'the computer sleep.
If a slider is set to 'Never', sleep is disabled for this feature. - Schedule button
Make sure you that you do not put your Mac to sleep accidentally:
- Pressing on the button / stop can put your Mac to sleep.
- Move your mouse pointer into a hot corner can put your Mac to sleep, depending on your settings from Mission control. Choose the Apple menu > System Preferences, and then click Mission control. Click on the button active corners, then see if any of the corners are set to "Display Put sleep."
- Using magnets near your Mac laptop can put your Mac to sleep.
If the previous steps do not work
These additional steps can help identify or resolve the problem:
- Reset the SMC.
- Reset the NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and screen. If that solves the problem, gradually reconnect your devices, testing each time until you find the device that interferes with sleep. And then check the documentation that came with the device or contact the manufacturer of the device.
- Start in Safe Mode to see if the problem is related to startup items not Apple, login items or kernel extensions.
- Try to isolate the problem by using a different user account.
If your Mac does not sleep or wake up when expected
Have a good.

I am using Bluetooth involved in the use of music made a software with sounds of digital instruments using a musical keyboard hardware connected via the USB cable to Lightning to play sounds from the app on my iPad Pro.
When I try to use a Bluetooth speaker source, there's a 1-2 second delay when I play a chord in the app and when the sound is played through the Bluetooth speaker.
This delay IS NOT the case when I use just the iPad Pro speaker on when I am attaching some small travel speakers to the headphone jack of my iPad.
Only when I try to use my Bluetooth speakers sounds better.
I use a keyboard master Korg MicroKey Air uses the USB port play their own Korg music make its app module.
Someone who makes music on an iPad with this problem at all?
Is this a problem question Bluetooth and/or iOS?
My iPad Pro isn't very strong using these apps do and travel speakers I use plugged into the headset jack music are a little better on the volume, but tend to deform when I try to increase the overall volume level.
I intend to put this issue on the web forums for Korg, but want some answers from anyone who has been playing and recording music on their iPad using an external keyboard to play and record music in an app to do the music.
Also, (and I intend to ask this in the GarageBand for iOS forums) can the iOS version of Garageband output sound on a Bluetooth speaker and quietly delay, too, that I can not get the iOS version of GarageBand to sound output via Bluetooth to a Bluetooth speaker.
Hi, MichelPM
According to the used speaker, he will always be * some * delay when using Bluetooth to stream audio from an iOS device (or practically any device BT also) through a Bluetooth speaker. I have a Bluetooth speakers system cheaper that I use with my iPad mini 4... I pretty much use it only to listen to sound. If I try and use it for Pinball iOS games I play, there is a delay of environ.5 second anywhere, I'm the speaker. Exactly same phenomenon occurs with the keyclicks when you type it on the iPad keyboard... 5 second delay & even with some applications of synthesizer iOS that I use (Animoog & Arturia iSEM). I think it's just the nature of the beast of Bluetooth.
Higher quality speakers would be better, but I'm not spending more money to find out.
If you want an immediate response with zero real audio keypress delay, I fear, the only way to do this is to use a wired speaker.

Random number 3 appears in the display when using the touchpad
I have a problem when you use the touch pad or keyboard the number 3 appears randomly and the number 3 continues to fill the area to explore text word or office. I restarted the laptop to factory settings but still have the problem.
could someone help.
Hi lennybytes,
Looks like the 3 key is suspended. You may notice the same behavior using an external keyboard?
In General, if certain keys n t work properly, you must replace the entire keyboard because there is no unique key that you can exchange. An ASP can order a new keyboard for you.
