Sry if asked before.. I think groupy is great - it's just what I needed but it's driving me crazy literally - windows jump across monitors and vanish - I mean they really vanish - cannot be brought back but apps still work - messages/emails still received but I cant get to them as the apps wnot maximise. Killing the app in task manager doesnt help. when I relaunch they open but remain hidden/working again.

Is it some settings or bugs? 

Win 10 pro 21h2 19044.1826
Groupy v1.5
Ryzen9 16core
Dual Samsung G9 both running at 5120 x 1440, Scale 100% always
RTX3080 Driver ver 511.65 (same problem game/studio)
64Gb Veng
Samsung m.2

Any help/advice appreciated..
