Hi ChrisSorry that you're having problems, I know how frustrating this can be.Since this works OK in the 32-bit version, you are likely looking at a driver problem for the 64-bit version.The only thing I can suggest, at this point, is to take a look at theNVIDIA Support Forums. There are some folks there that are using Windows 7 and they may have more information about this problem.Hope this helps.Thank You for testing Windows 7 Beta Ronnie Vernon MVP

ok i managed to solve the problemehopefully win7 is capable of using drivers of other os so i decided to try the x64 driver of vista for my 9800gt gforce and it solved the probleme so if anyone else has the same issue just try it

ChrisThanks for the update on how you solved the problem.Regards,Thank You for testing Windows 7 Beta Ronnie Vernon MVP
