Thanks for the quick reply. In an effort to find the problem as fast as possible I give you the code for how I create the D3D device. Perhaps you can see something that I cannot.
The problem with Win98 seems to be that the refresh rate isn''t initialized correctly. I always thought by specifying the refresh rate to 0, DX would choose a suitable one, but this seems to not be the case for Win98.
