The regular background in Inventor is light blue. When you start a "part" you must first "sketch" some "feature" of it then make it 3d using different methods (That Inventor in a very small nutshell

). The default lines are green (for non-constrained lines) and black (for constrained lines). Neither are showing up and you can't see the grid that is usually there in sketch mode

Well, what ever it was fixed itself without any encouraging beyond what we tried and that didn't work. We now have 7 of 12 200-333MHz computers running Inventor 5. 2 computers lack Inventor (but were suppost to have it) and the other 3 lack mice/keyboards. They don't run great, but enough for simple things like teaching how to do some inventor stuff.
