Workspace goes black

I was hoping this was just a feature of the trial version, but when I am trying to draw, move, or transform something, the workspace goes black, and I can’t really see what I am doing. How do I keep it from doing this?

This is ridiculous! I can’t even draw a straight line from point A to point B because i can’t see point B!

You can try changing the renderer type in the preferences. Some video cards react differently to Direct3D and OpenGL.

OK. That worked. Now maybe I can get something done!

But I had to restart the program for it to take effect.

Thank you.
