I am using Giraud Shading, and experience no graphics problems with any other programs. When I hit the reset button, it resets it, but to a "very zoomed out" state, see below.

I changed over to centerline graphics, and it only showed a white screen with a single dot in the middle. If I zoom in on that dot, after dragging a window around it, and after four succesive zooms, it is finally my model, that comes into view.

What's going on here.
