We have some forums located here:

In IE6/IE7 it pops up the following message while I browse the forums or upload attachments:

A Runtime Error has occurred.
Do you wish to Debug?
Line: 27
Error: 'document.getElementById(...)' is null or not an object

Unfortunately there isn't an error in firefox or safari so I can't just use Firebug to figure out where the problem is, or in what file. Does anyone know a javascript debug program for IE? Anybody with any guesses as to what it might be?
