When I try to open my 3D views, the scene window is blank and the 3D navigator window is black. Whats going on?
3D graphics cards typically do not manage their own memory use. Extensive use of 3D views can exhaust the memory in the graphics card, resulting in a blank screen. The easiest way to fix this problem is to simply restart the computer. Note: a “warm” boot is sometimes not enough to clear the memory in the graphics card. If a warm boot doesn t solve the problem, try turning your computer off and then restarting.
