The UI freeze

Compared to my previous post, I am trying to create an image to display in the user interface, which has a sweeping movement to go to the next/previous photo.

When loading of the UI, it creates 5 views of the image and calls setImageSource on each of them to load their photo. Only one of them is visible on the screen. When the user switches to the next photo, I slip into the display of the image that was right.

The problem is, when the first load of the user interface and the first image appears, the user interface events do not seem to get processed - maybe until all the 5 image views have completed their loading image?  You can drag your finger on the screen and nothing happens. Then, one or two seconds later, the gesture of hit plays itself.

This behavior is expected?  The lock of loads of image to the top of the user interface and get them to stop the event processing?

The way I had the time it was to use a bit of hackery. I tried the ImageTracker, but it had no effect. My guess is that the offset is not the actual load of the image of the SD card, as this happens before the. On the contrary, it is when the display of the image becomes visible on the screen.

To work around this problem, I have show 1 horizontal pixel of the image on the screen, even if she is not supposed to be on the screen, and I put its opacity to 0.1 so that it is not noticeable. When I do this, the event suddenly comes as could be expected without any lag before the next image on the screen.

  • Trackpad of MacBook Pro gets stuck and the screen freezes with pink and yellow lines

    So I'm really frustrated. I got my Macbook pro less than a year ago and Ive already had to get a bunch of replaced parts. I got my computer fixed as 3-4 weeks ago and they had to replace a lot of things (can't remember not what it was, but they had to remove all of the computer and replace some things that have been associated with the battery power /). Recently my computer did this weird thing where the screen freezes and pixelated pink and yellow lines will take right on the screen. In addition, the trackpad will be just stuck and I have to turn off my computer and turn it back on so that everything works. Someone at - he heard about something like that? I thought that maybe when I had my computer repaired they didn't replace not all properly? I did a check of the hardware on my computer (self-control an Apple recommended prior to an appointment at the Genius Bar) and he said that everything was going well. This poll looks like a hardware problem? Could this be a virus? Someone hack into my computer? I don't know, I'm just worried and frustrated :/

    Thank you!

  • Satellite A105 - 1/3 of the screen freezes regularly

    I have a Satellite A105 and the lower part of the 1/3 of the screen freezes regularly, but the top 2/3 of the screen is perfectly fine.
    After pressing the lower part of the screen or the border around the bottom of the screen for a while, it will go back to normal.
    After the slightest movement, it will begin to go haywire again.
    I was wondering if anyone knew if there is a problem with the screen or would it be the inverter?

    The inverter provides simply for the backlight voltage, he can't knock out 1/3 of the image.

    The problem is more likely to be the Module LCD or LCD Cable screen.

  • After the memory upgrade in Satellite A100-1401E the system freezes

    The laptop was initially delivered with only 512 MB of RAM.

    I installed 1 GB of RAM Kingston (part No. KTT533D2 / 1 g) into the remaining free memory slot. However, whenever I turn on the computer, the system freezes within minutes and I have to re - start.

    Is it because there is an uneven amount of memory in the 2 slots? I have 512 MB in each slot or 1 GB in each slot, etc.?

    I would like your advice.

    Have you tried to change places and put 1 GB of RAM in slot A?

  • Satellite A210-1UP - every few minutes the system freezes

    Hello

    I just installed windows 7 32 bit on a satellite A210-1UP

    Every few minutes the system freezes and then continues as if nothing had happened.
    No error or blue screens are displayed

    I would like to know if windows 7 can work without problems on this system?
    That is the version of the bios recommended to run windows 7?

    Thanks in advance!

    Kind regards
    Stijn

    Hello

    Yes, you can run Windows 7 on the A210.
    I ve got an A210 and installed Win 7 32 bit.
    It runs correctly without big problems.
    I have collected the drivers Windows 7 and install it on the system.

    Some missing Toshiba Software, that I could find in other series of satellites; for example, L500.
    Here I chose ve the VAP and Support utility Flash memory card in order to get the FN and the multimedia to work keys.

    PS: I no has not updated the BIOS as it was not necessary; everything is ok.

  • On Satellite M40-223 some games make the display freeze

    Hello
    I have a Satellite M40-223 with an Ati Radeon X 600 is.
    Some games (such as shockwave, world of warcraft games or never)
    Winter Nights 2) make freeze display and the crash of the laptop
    (accidents do happen after the same amount). I downloaded the drivers
    on the toshiba site (16/11/05, 6.14.10.6534 drivers) and nothing has
    has changed. Then I downloaded the latest drivers from the ati site
    (http://ati.amd.com/online/mobilecatalyst/) and removed the older
    (following the instructions of ati). The display freezes always but
    Sometimes the VPU recover the previous session.
    What should I do?
    I will try to uninstall these drivers and install the ones toshiba
    Once again? When I installed the drivers from toshiba for the first
    I did use uninstaller first, time could this affect the most recent configuration?

    I will try to use the omega drivers?

    Best regards

    Laura

    Hello

    It s not advised not to use the graphics driver from Toshiba. The other drivers don't support the overheating protection. The games are a high performance programs. If these applications are running on the laptop all devices must operate with maximum performance and produce a lot of heat. The high temperature could be responsible for this gel and close downs.

    I read in the forum that you can install the other drivers (not Toshiba) at your own risk.
    I think you should check the fans for dust and debris.
    Sometimes the cooling modules may not cool properly because the dust and, therefore, these problems occur.
    Additional do not forget that there is enough free space around the laptop to the airflow correctly

  • Portege M800-106 the system freezes when I connect a device via USB

    When I connect a device through a USB port, the system hangs. This happened with any device even something that has been used before. Example - if I turn on the printer /plug in my Blackberry to synchronize the .laptop just going so slow that I have to do a reboot with the devices still connected to get the system working again. Running Vista. Any help please?

    Hello

    You see yellow exclamation marks in Device Manager? Maybe a driver isn't installed properly in the system freezes.
    In addition, I would try to remove the USB ports in Device Manager. After this restart your laptop and USB ports will be recognized again.

    Have you tried a BIOS update? If this isn't the case, you should do it. Before you begin the update, close all running programs and make sure that you are logged on as administrator.

    Last but not least try to reinstall Windows using the Toshiba recovery disc. It only takes a few minutes and then you have settings to factory again! :)

    IPhone 5 c of the girl freezes a lot.  We took at the Sprint store and they can't find anything wrong with it.  They tell her to delete photos to make a storage capacity.  Any other ideas?

    How much free space is a iPhone? Use the settings app to find out.

    Settings > General > storage > storage section is at the top.

    Did you remove photos from the film? If so, the photos transferred from the recently deleted album. They can remain there for 30 days allow for their recovery. But if you need to free up space on the iPhone you should remove again the album photos recently deleted.

If you can describe the exact screen it freezes, as well as all the details (indicators of progress bars progress, messages or guests or spinning, etc.), which can be useful. You can find the following article useful to identify the different screens you see during the boot process:

  • The mouse freezes at startup properly off. Mouse only thaws and works correctly when I hold the power button to stop and turn back.

    I just got a new Inspiron 1545 computer 2 weeks ago and it works fine but I got a problem for the last two days where my mouse will freeze after that I stopped it using the stop option. When my computer starts you can move the mouse, but after a few seconds, it freezes, and you can't move the mouse but the keyboard works. I try to restart the computer with the option to reboot from the start menu and when it starts up to the top of the mouse freezes still. No matter how many times I try to stop or restart properly mouse unlock not. It only works if I stopped it by pressing the power and then switch on again. Any ideas as to what I could do to fix this?

    The sad truth is that the mouse freeze problem is back. I searched the forum for other solutions, but so far without success.

    I am currently using MS Wireless Mobile Mouse 3500 and just to make sure that the problem is with the mouse, I inverted this mouse on my other laptop which works also on Windows 7. Mouse freeze problem is replicated, which never happened before for my other laptop.
    Conclusion, until Microsoft is able to solve this problem, I opted for Logitech. I bought a Logitech M235 wireless mouse last night and keep your fingers crossed that the mouse freeze problem will disappear.
    Life is too short to be stressed more mouse freeze problem.
