I just loaded up last week and saw this problem. However, I pressed PG_UP button and it shifted the view automatically to where the ovals became circles again. CoCreate automatically started up with a view that appeared you were looking at the object plane at an angle; page-up appeared to shift the view to where you were looking at the plane at perpendicular angle. I'm sure this is in the documentation somewhere, but I found it somewhat accidentally. Try this. (I didn't modify any graphics settings etc. as the rest of the UI looked fine; I assume if you were having a problem with graphics drivers per other suggestions, your entire window would look distorted.) Hope this helps you!
