Can't switch Apps


  • I've dual booted my Win7 PC with the Win8 Dev Preview, and it's all installed and activated and seems to be working fine. The only problem is that I can't switch apps by dragging/clicking on the left hand side of the screen. Alt-Tab and Win-Tab work fine, they switch apps with no problems, but the aforementioned method for switching apps doesn't work, which is disappointing, because I really like it. I've re-installed Windows 8, and I'm still having the same problem. Previously I have installed Win8 in a Virtualbox virtual machine, and have had no problems at all, the left side dragging/clicking app switching was working fine. Any help will be much appreciated, thanks.

  • Hey there,

    What resolution is the screen set at? What if you try with different resolutions? Does that fix the problem?

  • The screen is set at 1280x1024. I tried setting it to 1024x768 and it still didn't work, then switched it back and still nothing. In my virtual machine it worked fine at both those resolutions. I'm starting to think it might be a windows process that isn't starting when the PC boots.

  • hi, I have the same problem, my resolution is 1360*768...any idea?

  • Something I've just discovered, whenever I have the Task Manager open and selected as the active window, the app switching works just fine...weird.

  • same here, maybe it's a bug.. hope they will fix it with updates..

  • Few thing you need to make sure.

    1. Display should be above 1024x768
    2. UAC should not be disabled
    3. Make sure you have display drivers are installed properly
    4. Some display vendors like ATI has tweeted that you'll be getting driver updates through Windows Update, so make sure you apply all the Windows update.

  • 1. My Display  is at 1280x1024

    2. UAC is not disabled

    3. I installed the NVidia 285.27 Beta drivers to try and fix the problem, but it didn't work. Hopefully it is just a bug with the graphics drivers and it'll get fixed soon :) Also, my GPU is a 9600GT.

  • exactly the same problem here :S

  • Thanks for all of the detailed bug reports, we're trying to track down what might be going on here.


    To summarize, several of you are unable to navigate through the back-stack using the left edge of the screen unless task manager is the active window (but alt-tab works)

    Have any of you with this problem used the registry key trick to enable the old start menu?

  • No sir i didn't used any registry trick and i really don't know why i get this issue while my pc it ran win8 rather well without any issues, i have installed it from September 15 with all device drivers and and updates but still i'm facing now that issue and even after doing re-format of win8, so i think it might be a bug and hope you can fix as soon :)

  • Nope, I haven't touched the registry at all. I quite like the new Start screen :)

  • Hey, it's working now! :D

  • @lamboman007 really ?
    Monday, October 3, 2011 9:10 PM
  • @lamboman007 what kind of updates have you installed ? because in my windows update it says "your pc is up to date!"

  • Just checked my update history, turns out that the update was a Definition Update for Windows Defender. So, I don't think it was the update that fixed it then. I seriously have no idea why it's working now, nothing else has changed... :/

  • Have had this same error. I you have some Metro apps opened try ending them with Task Manager and then attempt to snap either to the left or to the right of the screen. Try waiting until the window snaps. Does NOT work for me perfectly. Sometimes I can't snap windows as well.

  • Are you using 64-bit OS flavor?
    Well this is the world we live in And these are the hands we're given...
    Tuesday, October 4, 2011 2:09 PM
  • yes im using Windows Developer Preview X64 + Developer Tools with Windows 7 x64 dual-boot
    Tuesday, October 4, 2011 3:53 PM
  • Seems like 64-bit version has glitches with snap.

  • Hmm you're right, im going to install 32bit version but do i need first to install Windows 7 64Bbit or Windows 8 32bit for dual booting ?

  • hi mates!

    I don't know how exactly that is activated cause without restart that app won't work!
