Hey John,thanks for the reply.As long as it helps to change window size for special menus like PMDG options it is usable, but getting the menu bar visible takes at least 4 to 5 seconds most of the times. That is a little annoying.I also think is a driver problem cause all users who seem to have it also having a Nvidia card.Hope it will be fixed in newer Windows 7 designed drivers.But by the way I really enjoy FS9 on Windows7, it really gets the last out of my not the newest system. Loading times are faster than with XP (virgin FS9 that is of course). Maybe that is because of a more optimized dual processor support.Cheers,Markus
