I thought it might somehow be a scripting issue, so I disabled all the scripting in IE, but still can't replicate the problem - very odd indeed. Maybe somebody else will see somthing I missed.
Ha yes, got it! Norton Internet Security appears to be sneaking in some javascript code - SymError(). This appears to halt page execution in the event of finding a javascript link containing the string 'ad' or 'ads'...
is the page supposed to have ads? cuz I didnt see any with either IE or Firefox, and if its supposed to have them, then my Norton is doing just that :P
I'm running Norton Antivirus 2k5 if you need some testing done :)
