Problems using Windows 2000

I’m beginning with OpenGL and a made a little application in VB6 using WinXP and it works ok, my problem is that I try to run the same application in another PC with Windows 2000 and it just doesn’t appear anything, can anyone give me any tip about this? Thank you.

The opengl app is heavied depend on the graphics card and card driver and of cource can not expect the same program can get the result on different PC.It would be pretty hard to figure what cause your problem,but more often than not ,you could check out the card and driver issue first.
