SwapBuffers crashes on Intergraph


I aleready posted this in Advanced programming section… but it may be a hardware issue so… her it is :

I have an aplication that runs fine on NT4.0 and W2000 with nVidea and Voodoo cards.

But when I try to run it on an Intergraph (Intense3D) with a RealiZm II VX113A-T video card (W2000 Server + SP1)

the application exits… I debuggend it and it appears that

SwapBuffers() is returning FALSE (error)

GetLasterror() reports “Access denied” (huh?)

Anny ideas ?



Update : if I disable hardware acceleration it seems to work…
