Problem with HP Media Center 864N PC Desktop
Disable the Grab Pro and Octh Class add-ons can solve the problem1 Solution
I upgraded from IE6 on my XP SP3 box, and then it took forever on page loading after I entered a site but other browser run smoothly.
After searched over the Internet and found Feran's suggestion (http://social.technet.microsoft.com/Forums/en-US/itproxpsp/thread/9c183173-3cdb-4a96-a6dc-bfb1320565df) to disable some add-ons. Yes! it's Grab Pro that comes with Orbit I installed before upgrade.
