Hello fellow simmers,lately I've been experiencing very strange behaviour simming in windowed mode. When the cursor is over a click spot (i.e. it changes into a hand) part of the panel disappears revealing another panel underneath ! This other panel reflects a situation earlier in the flight. This only occurs in windowed and 2-D mode. It also occurs with sll my add-ons, PMDG 737 and 747, Embraer Legacy. I tried reinstalling fs9 but no luck.I hope someone out there has a suggestion.

Are you running a NVIDIA card with the AA higher than 4X?Cheers

I run a 7900 GTO 512 Mb but anti-aliasing is set to x4.I also noticed the picture of the aircraft is now missing from the "create a flight" window. I tried deleting the fs9.cfg but could not start fs9 anymore, it just crashed. So I restored the old FS9.cfg and still have the same problems as before.
