LOL, I never read this thread after my initial post. Sorry! I didn't even really have much to offer anyways -- all I had to do was fire up Dgvoodoo, use the CA.ini fix, apply G+'s compatibility database, and put it in Windows 95 compatibility mode. The sim ran great for years of using Xp x64, but one day I fired up LB2 to discover I had some other issues (namely speed) -- they made the autopilot crash me, SAMS shoot at superspeed, etc etc. I never discovered whether an update or driver change broke it, but it did run fine for a very long time.
