Swapbuffers() fails

Hi,

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 ?

Thanx,

U.P.

Have you checked that the rendering context was created in the first place?
It sounds like the pixel format you requested is not recognised.

Yeb, I check every handle at startup…

The strange thing is that, if I disable hardware acelleration on the Intergraph machine the software runs fine…
