I've done another test on an IBM ThinkCentre with a nVidia GeForce 7900GS.
Under WinXP SP3 the error (i reported at Post #1) appears.
On the same system, installed with Windows 7 Enterprise, is the OpenGL-Animation on the DL-165 adapter slow, but it works !
Unfortunately, the device useless for us, because we are using Windows XP SP3 on all systems.
What a Shame !
