OpenGL & Win2k

Well my project runs with Win95/98/ME perfectly but not on Win2k machines. And I think OpenGL is quite os-independent in comparison to DirectX. What do I have to consider to make my prog run on win2k.
I use OpenIL(or DevIL) and several other functions mostly from NeHe. can someone give me some hints?

what do you mean it doesn’t run. i assume there is at least a error message.
could you be more specific.


Oh…well I don´t recieve an errormessage. The programm just changes the screen-resolution and then crashes and ends.
Maybe I should build in some errormessages, you´re right.
But I thought there is some general stuff to note…
