Shuttle Pro2 user for nearly 2 decades - not only with Vegas, but the many other apps Contour supports. It's a wonderful if not critical tool. I also double as an IT Professional, owing back to disassembling boot sectors back in the Atari 6502c assembler days.

Setup: PC / Windows 11 current / Vegas 20 Pro. No other applications running - Vegas Pro 20 is it.
Problem: Vegas 20 Pro loses focus on the Shuttle Pro device - i.e. forgets it's there.
Symptoms: Vegas boots, loads the project file, Shuttle is there, works perfectly. Shuttle through a clip, and all of a sudden, it's non-functional.
Workaround: While Vegas Pro is running and has focus, open the Contour Control Panel app and leave it there. When Vegas loses the Shuttle - i.e. no longer responds - alt-tab to the Control Panel, click it, then alt-tab back to Vegas. Voila, Shuttle is back and perfectly functional. Until it isn't.

Not a roadblock, in that the workaround always works, but man, it's getting annoying having to frequently alt-tab/left-click in the middle of an intense session, just to alt-tab back again.

First time I've ever seen this, in all the Vegas iterations I've had going back to my first experience with the Shuttle + Vegas 5.

Maybe Windows 11 stealing focus perhaps? Dunno - thoughts anyone?
