oooooooh so I’m not one here with more problems. (pls understand that I have this problem maybe about month and expect my own USB devices problem at PC, generally so no reason post this on Forum).
I had this Mouse hide yesterday. What is really strange, also pedals are off, no sound of USB disconnect event, simply LED on Saitek off 
During flight I do sometimes contributions here so I did ALT-TAB to Win desktop and my screen appears with Forum but no with bottom win pane with Icons, it appears as some lag timeout after while 
I’m afraid that AAU1 (memory leak not correctly tested??) or Gaming services with Servers does bad things. What is happening to sim again???
