Better yet, grab the free copy of chapters from Kevin Yank's book and setup your own test server (I did years ago and don't know how I could have survived without it).

In other words, East Coast is correct. You've overthought the problem and made it impossible to troubleshoot.

Of course, my first inclination was to chastise you for using IE which is known to cache files until hell freezes over. When you're changing files and testing, that gets in the way. Use a good (DOM-compliant) browser then test with IE to patch your code for that piece of $#!T.
