What’s this? You’re having trouble running OpenGL apps on WinXP? Your problem is truly unique. It’s a good thing you posted it here right away without wasting time searching the archives. </sarcasm>
Try installing the display drivers for your video card. You can find these on your vid card manufacturer’s website. If that doesn’t work, try upgrading to Windows 98
