I'm not having any problems (2 monitors running off NVidia drivers), but I did just notice that Windows 7 is now switching to Basic (not Aero) colour scheme when the game is running.
It never happened before, and it doesn't happen with any of my other games except Flight Simulator X (which was released before Vista and Aero were around).
Seems to indicate an issue with the graphics, possibly related to the other issues that have been reported.
Edit: Thanks ForkTong, and fair enough. As I said I wasn't worried, it just seemed unusual - and your game is one of the few stable enough for me to regularly alt-tab out of it without risking a crash
