When I install det. drivers newer than 22.80, my OpenGL setting go wierd. If I uncheck the 'Enable buffer region...' or 'Allow the dual planes...' and exit, when I go back in to display properties the values are checked. Then, if I enable anisotropic filtering, the Vertical Sync changes to 'Always on' when I exit and come back in. If I change the Vertical Sync to 'Always off', exit and come back in, the anisotropic filtering is disabled. Suggestions?

Win 98SE
Asus V7700 GeForce2 GTS

try using drivers from asus and see if you still have the problem.
