The good news is that I have managed to integrate CuteChat with our Plumtree Portal.  The bad news is that it's not working on all client setups.  Here's where we stand, from the client browser perspective:

Firefox on any system: works beautifully
Internet Explorer 6 with SP2 on Windows XP: works beautifully
Internet Explorer 6 on Windows Server 2003: getting the error: 'XMLHttpRequest' is undefined

The strange thing is that I can load the demo on your website from our 2003 server, and it works fine.  It's just when I try to load our Chat setup.

Any ideas what might be going on?

Thanks!
