I was using Windows XP in full screen, running the 3D software DAZ studio. Everything was okay (it even seems to use OpenGL okay) except for dragging with the mouse - whenever I tried to move the camera, or drag any of the adjustment sliders, I could only drag in one direction, and then only in giant leaps so the camera would leap off into the distance, or the settings slider would jump to to several thousand percent. If anyone wants to try it, you can download DAZ Studio for free at www.daz3d.com.
