Hi all, i''ve got a problem running applications created using the directx appwizard in vc++ 6. For example, if i create the simple trianlge example, i can compile and run it but after about 2 minutes of rotating the triangle about my PC just freezes! After hours of debugging i eventually decided to reinstall everything. I now have a clean win2000 pro with sp2, vc++6 with sp5 and the latest dx8.1 sdk. I have the latest video drivers for my tnt2 yet my PC will always crash running directx appwizard programs. Does anyone else share this problem or know of a way to fix it? Great forum by the way, TOny.
