IE is nasty at 'caching' pages, and especially with forums, with so many threads and messages, sometimes if your pages are 'hanging' on submissions, or waiting to cycle to another section within say, this forum, but yet your IE pages viewing other web pages seems fine, it's best to go to your IE Tools, Internet Options, and delete the cookies and files caches. This sometimes helps.

Also, not having numerous toolbars installed is a help. With the upgrade to the higher service packs, this has been a conflict with all the 'pop up stoppers' and the cycling of pages and the pages loading to your computer for quicker refresh rates. Also changing your IE settings to get new data for every page visit slows it down too.

Just trying to offer some pc care to those that are suffering with the lags and hangs. (Mine does it off and on too... So before I hit the 'continue' button when posting, I copy what I have written as a 'just-in-case'... LOL.)
