I tried the option and restarted, but it did not work. I did try my desktop rather than my laptop, and the desktop did not have the issue. So I am assuming it is some sort of grpahics card/driver issue with my Dell laptop. (Mobile Intel 945GM Express graphics) Thanks for all the help.

You are perfectly right. Mobile Intel graphics don't work well with SU. The only thing you can do is to turn off Hardware Acceleration (Window>Preferences>OpenGL tab), but SU will be quite slow with all but the smallest models.
