Life experience has taught me that "I am not alone"....If it's happening to me, it's probably happening to others.

Aparantly IE has a problem with some JS and its coding...and it won't always happen on every IE out there (as you'll see from the posters' experiences). You may want to review the thread to see if there's anything in it that's relevant to your site which could be causing my IE to error out.

I normally use FireFox but the IE I'm using which gets the error is IE 7.0.6001.18000
