Toolbars sometimes don't launch

[hirschor]

OK, it just happened again. I turned on logging of window events, and all I saw was:

Window event logging started.

I then clicked back and forth on multiple different windows, and it had no effect. No window events were picked up by QM at all.

I did the same thing on another machine that was working normally and saw:

created 33950700 "WindowsForms10.Window.0.app.0.3ce0bb8_r18_ad1" "TimerNativeWindow"
created 34016236 "WindowsForms10.Window.0.app.0.3ce0bb8_r18_ad1" "TimerNativeWindow"
active 263956 "WindowsForms10.Window.8.app.0.3ce0bb8_r18_ad1" "PowerScribe 360 | Reporting"
active 460818 "IEFrame" "Radiologist last known locations - Windows Internet Explorer"
created 34081772 "WindowsForms10.Window.0.app.0.3ce0bb8_r18_ad1" "TimerNativeWindow"
name 265252 "SunAwtDialog" "Work Modes USER: Argle, Bargle Server IP Address: 10.20.2.50 Current Time: 4:22:04 PM "

Looks like when this problem occurs, QM sees no window events at all.
And the low level hook setting did not help either.
