I have experienced this problem due to corrupt files in the IE temp folder also. Don't know exactly the cause but the fix that worked for me was logging into XP via the admin account and actually deleting everything in the temporary Internet files folder.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
