I recently reformatted my computer and reinstalled windows 2000 prof on it.  I also downloaded and installed internet explorer 5.5.  That is what i had running on it originally.  I have installed all of the most recent drivers for each device and everything is working great except IE.  Whenever I scroll on certain pages...including these forums....the windows keeps flashing a lot.  Almost like a strobe effect on the page.  Has anyone had this problem, or does anyone know of how to fix it?
