Black screen entering menu fs9 win 7

Last week i installed win 7 x64 With succes i installed fs9 with all my addons, but the following problem occured;When i am in fullscreen mode and i want to enter (for example) the PMDG-menu, the screen turns black. After pressing Esc, it will go back to the cockpit. I only have this with addons in the menu. Not with default fs menu. FspassengersPMDGWilcopub FSUIPCetc....Strange thing is that if i open fs in a window there is no problem! I've tryed al lot of things, but non of them are ok.

Solution that i found was to turn of the AA-setting in fs9.
