PUBLISHER- changes color of font, has glitches

Okay, I have been using Publisher 2003 Pro, but it started acting up about a month ago.  It changes the font color (red for blue, pink for orange, etc., no matter what I do) and acts like it's about to freeze up on me, then it jumps around on screen (the whole document). 

Tired of this, I went out and bought Publisher 2007, full version.  I uninstalled 2003, installed 2007, and it's doing the EXACT same thing!!! 

Any ideas would be greatly appreciated.  (I am running Windows on a Bootcamp partition of a Mac, but I've never had any problems with it.) 

Thanks, Darynda...
