Wormhole

Okay now that I have your attention with a catchy name.  I have this cirle that appears on my display only in solidworks.

Attached is a picture seen in every file including a blank new one.  I just got a new harddrive and a new 2009 reinstalled so I have no idea what this circle is, how it got there or how to get rid of it.  So far SW has crashed once on a large assembly and I just checked my video driver and it is certified.

Any clues?
