Disable pop-up blocker...obviously seems like spyware is a common issue in here so that could be it. There's a particular one that shows up as something like "Web Tools for IE" or "search bar" that totally jacks JS - you'll forgive me but I don't remember right off hand. Another thing you can try is to install the latest Windows Scripting host from MS...the install includes a new jscript.dll so I've had luck fixing a few with that. I just go to google and type in "download Windows Scripting host" and follow the link from MSDN. You can try this link: http://www.microsoft.com/downloads/d...displaylang=en

I doubt this is the problem...usually it's the spyware or pop-up blocker, but just in case.
