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.

I was able to reproduce that here so we've added it to our list to look into.
Thanks!
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!

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.

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)

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?

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 )

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.

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!
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!
