This seems to have started an update or two ago. Now, when I have a session open, and I return focus to that session from some other application, there is a disruptive Windows 'booonngg' before I can actually do anything in that session. In other words, the first click to the session triggers the annoying sound, and only then do I have actual access to the session (two clicks to begin working versus one). Anyone else having this happen in a current version of Windows 11?
I've seen the same issue a couple of times. It looks like this is related to the MS RDP ActiveX control as it only happens there. So far we haven't found a solution. The RDP ActiveX is closed source from Microsoft therefore we can't really see what's going on.
Thanks for confirming it's not just me, Stefan. Maybe Microsoft will make another change that puts things back the way they were!
