Interface, jQuery, and Internet Explorer

Site: http://social.kcstar.com/users/1
Demo: http://interface.eyecon.ro/demos/sort.html

Ok...so I am building a site and making it so users can move "blocks" around on a page. Everything works fine in Firefox, but it dies HARD in IE6 & IE7 (re: they both crash).

I have triple checked the code that is being run vs the demo and there is not 1 piece of code that they do not have (I commented out the "storing" part in my code).

Obviously this works fine in IE in the Demo...anyone want to give me an extra set of eyes to see what could be the problem? Maybe it is my computer?
