I would suggest to try to modify the hardware acceleration level of
your video adapter.  On XP, you can get there by right-clicking on the
desktop, selecting "Properties", then clicking on the "Setting" tab,
then "Advanced", and then click the "Troubleshoot" tab.  Try lowering
the hardware acceleration level there.
