Hi all,I'm helping a friend with FS2004 that I tried to help on the phone tonight, and I'm wondering if anyone may have an idea of what is happening with his systemHe has an Athlon 2600, Gigabyte GA-7VRX, ATI 9800 Pro (128M). It all stated when installing the game LOMAC(sp?) last weekend. He had trouble running it, so he called LOMAC tech support- who told him that the DirectX 9.0b he had on Win98 was a bad version, so he upgraded to DX 9.0b. Now he had LOMAC working, but the textures flashed, as they do in FS2004 now (on the plane that he flies, not the AI traffic). The tech suport guy told him to update his video driver, so tonight I walked him through updating his ATI 9800Pro to the Omega Cat 4.2's. The textures still flash, but can be mitigated by turning off T&L, or unchecking "reflections" on the Aircraft/graphics menu.I don't have Win98, nor an Athlon, nor LOMAC, so I'm out of ideas. Can anyone please help with any suggestions?Thanks,Bruce.

Upgrade to WIndows XP if possible.
