I too just installed it on XP, and it seems to work fine, some add-on aircraft won't show but in the 2002 downloads you can get the MDL repair utility, works great and easy!!!!
Only bugs I have noticed (uncertain if these are XP related??) is after adding some new sound files of bullets and flak, it messed up my sound card settings.
Another thing is I notice a majority of the C47's will be flying inverted?!!!!!
Give it a try set up a Quick Combat, you against a fleet of C47's and let me know if you see at least half of them flying as if Ozzy where at the yoke!
At first I thought it was one I shot at (was practicing and wanted to practice on something that wouldn't shoot back

) but happens often
