The problem only started a few days ago. Basically, whenever I move my mouse around in IE6, iexplore.exe starts using up the CPU like crazy. What's weirder is that when I login as another user (or simply run IE6 as another user) everything works fine. I tried clearing the cache, deleting the history and cookies, and even manually deleting all of my current user's index.dat files (as was suggested to remedy a similar problem), but nothing helped. I suspected that maybe a nasty piece of Spyware was causing the problem, so I ran Ad-Aware and SpyBot, but they didn't turn anything up. I even ran Norton Antivirus with the latest definitions on all my hard disks (over 140gb of data, which as you can imagine took a fair bit of time) and came up with nothing. I use Mozilla for just everything I can, but there are still a few tasks that I *NEED* Internet Explorer for, so please don't tell me to just use Mozilla/Opera. Any ideas?

Have you updated Window lately? If not you might try that. Does it happen all the time? What if you are not viewing a web page (type "about:blank" in the address bar)? Only on certain pages?

Sorry, I forgot to mention a few things: Yes, I installed all the updates and fixes from WindowsUpdate. And yes, it happens on all pages, but to varying degrees. For example, when browsing the default MSN home page it only goes up to about 50% usage, but on just about all other "real" websites it goes all the way up to 99% as soon as I touch my mouse. And as soon as I let go of it, it drops back down to 0%.

I'm having the same problem, doesn't anyone have any fixes out there? :(

I'm having the same problem!! GRR. Any solution yet? I think this is a new bug or something going round. I hope that it gets addressed SOOOOOOOOON! I just logged in a differt user and it runs FINE. Hrm. Anyone we can contact? Microsoft?! then we'll have to pay for their mistake!! grrr

I get the same issue - 99% iexplore.exe - but it's only really crippling on pages with forms (Mapquest, Orbitz, etc.), and removing the auto suggest isn't a solution.

This just started on my laptop yesterday (winXP SP!, IE6 SP1, all the latest patches). If I open explorer, iexplore.exe hogs all the CPU and nothing happens for ages, even if I'm off line. Eventually the explorer window opens but it is still very slow. Usually I kill the process before that. However, explore.exe is fine, and I can therefore browse the net by using Windows Explorer instead. I have the latest Norton AV definitions, and nothing has been picked up. I tried a system restore but it failed... Any ideas?
