I am using Joomla 1.0.12 and Bridge 1.17, with a wrapped forum. I use firefox, so I didn't notice the problem until some of my IE users reported it. When a logged in user views a board, internet explorer loads the page, but then freezes for 10 seconds, with 100% CPU useage. You can't scroll or click anything in the browser during this freeze. Any ideas what could be causing the problem? I was thinking it might be the "Jump to" list loading at the bottom, since we have a ton of different boards. Please help.
Can we see a URL?
If its IE7. Its probably their memory leaks.
I've noticed it can build up a considerable memory leak where Ajax and/or flash is used. (but not just limited to smf)
It could also be IE choking on some JavaScript. Can you see if there are any errors reported on that? Firefox will report it in the error console (Tools -> Error Console), IE will report on the status bar at the right with some really unhelpful messages when you open the dialog. Also check and see if it is version related. If you can betermine if a specific or many versions of IE are affected, that will help in diagnosis.
Thanks for the suggestions everyone. My site has tons of different boards, so it turned out that IE was choking on loading the "Jump to" menu at bottom of my forum. I removed the "Jump to" pulldown menu from the templates and it works great now.
