Are you trying to run from IDLE (starting from the desktop icon), or by 
double-clicking glinfo.py? If the latter, you would only see a black DOS 
window briefly and no regular output window. However, if you double-click 
any of the other programs (e.g. bounce2.py), you should see a 3D animation.

One thing to try is to go to the web site of your video card manufacturer 
and download the latest version of the video driver for Win2000. This is 
often the problem, because VPython uses the OpenGL graphics machinery, and 
video driver support for OpenGL has been improving with time.
