When im on the internet the pages jump up and down causing massive lag. The pages I view move up and down rapidly, not much more i can describe other than that.... And yes ive downloaded IE7 but i use Mozzila
I would uninstall IE7 and do a system restore to a date before you downloaded IE7. Let me know how you make out.( It sounds weird, because you don't use it, but it makes everything buggy)
