I realy noticed these first time with the SU9. Right click to look around and all instruments etc will freeze as long as I press the mouse button. Thus, voted…
Not sure, but I would say it was not present before or I realy not noticed it because I usually use TrackIR.
note: may we have similar topics with the same cause: example: Joystick won‘t react when pressing the right mouse button in cockpitview since sim update 5
