Why are you changing those window styles exactly?

I have trouble with a Group which includes Adobe Acrobat if the window is maximized. If the window is not maximized, the Group behaves as desired, that is, I can switch between apps in the group and the Windows cursor behaves normally. If the window is maximized, the cursor typically locks up, and I can't switch to another app in the group. Sometimes using Window Detective to set WIN_EX_APPWINDOW causes the cursor to resume normal behavior.

winver = 21H2 22000.795
Groupy = 1.50
Acrobat Pro = 2022.001.20117

I purged, rebooted, freshly downloaded Groupy, installed it, & rebooted. The behavior of a group containing Acrobat Pro DC is the same as before: Acrobat locks up the group when maximized & behaves normally when not maximized.

Thanks for the suggestion!
