In Kennedy's case, this is almost certainly caused by the addition of the 
second monitor.  Specifically, in some versions of Mathematica, graphics do 
not work if there are multiple monitors connected to the computer *and* the 
monitors are not all set to the same color depth.

So, fixing the problem is generally pretty easy...simply go to the Display 
control panel, and make sure that all monitors agree on the "Color Quality" 
setting in the Settings tab.

If you don't have multiple monitors, this could also be caused by running 
NetMeeting.  NetMeeting works by creating a second virtual monitor which 
runs at 16 bit color depth.  Quitting NetMeeting or setting your main 
monitor to 16 bit color depth will fix that problem as well.

This issue has been fixed in recent versions of Mathematica (I can't 
remember exactly when, but I'm pretty sure since at least 5.0.1).
