I had this problem when i updated IE 6.0 with Sp1. I had to uninstall Sp1, but l8r found out it was becoz of TSRs taking up a lot of RAM, so for me the option was to either free up RAM by killing nonessential TSRs or increasing RAM! i did both : increased RAM frm 256 to 384 MBs and killed some TSRs i didn't reaaly want!!! U can try this and mebbe get over ur problem!!!
