Hi, I just stumbled over a difference between 8.0.30 and 8.5:
When I make all Windows (Project window and Mixer) independently Floating and move them to other Screens - i.e. the Menubar stays on the original Screen, I experience now (with 8.5.) a bug: If I open ANY other window in that Situation and Close it again, None of the menus can be selected any more until I minimize the application and maximize it again.
This was NOT the case in 8.0.30.
PS.: There appears to be some random switching between the “small menu bar” and this Grey-ish Background, but the menus are no longer selectable, see above.
