Thanks! I've done some more testing here and was able to reproduce this, and it's caused by DisplayFusion not having uiAccess because it's running outside of

C:\Program Files

. Some permissions like uiAccess in Windows require the application to be both signed, and installed to

C:\Program Files

. If you uninstall DisplayFusion, then re-install it to

C:\Program Files\DisplayFusion

, that will fix it up.

Sorry, to clarify, could you update to 12.0.1 again, and then send the troubleshooting info using the steps in my previous reply?

Thanks!

I've setup another machine for testing and was able to reproduce the original issue here. We'll take another look at this and hopefully get it fixed up.

Thanks!

after roll back to 11.11 it doesn't work either, but the problem is differenet.
When Adobe Pdfreader ia Active window - after ALT+TAB Panel is ahown and remain on the screen, bud only second pane is selected nad the selection doesn't move by pushing TAB. See tachment

It works correct if any other app window is selected as Active.

If you roll back to 11.1.1, do you still have those two issue?

Hi,
I am not aware to set anything special in Adobe.

I realized yesterday that tab switch also doesn't work correctly when I have more then 44 windows opened (11 page icons in one row x 4 rows, the problems start when adding first icon to 5th row )

Still no luck reproducing that issue here with your DisplayFusion settings imported. Are your Adobe Reader settings all defaults or have you changed any of them?

Thanks for the video! We definitely haven't been able to reproduce that issue here. Could you send me a backup of your DisplayFusion Settings? (Settings > Options > Export)

What version of Adobe Reader is it, and have you changed any settings in Adobe Reader from the defaults? We've tested here on multiple machines and can't reproduce this behaviour.

We haven't been able to reproduce this issue any more with the 12.0.2 Beta 6, released today. Could you give it a try and let us know if you still run into this issue?

Thanks!

Hi,
If the Active Window is Adobe pdf reader than after Alt+Tab the popup window with all active apps shows for very short time (few mililseconds) and then it disapear.

Alt+Tab works correctly in all other cases.
