Recently I installed Vista on my machine, and since then I've been running into LOTS of problems. The clipboard has been buggy, appearing darkened out and the "flip out" section used for E6B, etc., constantly spins around the ring. Generally if I reboot the PC it corrects the issue, but I find I'm having to reboot EVERY time I go to play.
Also, while not a new issue since I upgraded to Vista (I originally played on XP) is that unless I alt-tab to desktop and back to the game certain graphical features (specifically ship wakes, clouds, damage decals) don't display properly, often times incorrectly being tiled across the entire screen. Ground objects also vanish from certain angles. Alt-tabbing out and back in fixes this and for the rest of the time I'm in the game it's fine. What IS new is that before Vista I didn't have much trouble other than a bit of inconvenience of having to Alt-tab in-flight (doing it in the tower didn't always fix it). However since I updated to Vista this has been causing the game to freeze, meaning I've wasted the entire time I spent hassling to get it running in the FIRST place.
