I just got a gateway computer dedicated to blender 3d!
Problem: When I push “B” for box it does not show the box dimensions on the screen, although I can click and drag to select vertices. (I just can’t see the box/field of interaction)
Problem: The render window does not show my render progressing. It does not show a finished render until I move the window itself.
I’m thinking both of these problems are related, possibly to monitor or video card?
I had exactly this problem when I built my Vista box. If you’re using an Nvidia card, try disabling antialiasing in the Nvidia Control Panel -> Manage 3D Settings.
Another strange thing: When I go to 16 bit instead of 32, the box and render progression works fine. But of course the picture on the render is banded!
