Hey all - thanks for everyone's replies. I think I finally figured out the prob. I have always had Mozilla Firefox installed, but for some reason it is now fighting with my internet explorer. (why can't we all get along?? ) As long as I log on using Firefox and not internet explorer I can access chat - never used to be like that, but obviously something changed. It's a pain in the butt, but worth doing to get to chat.

Thanks again.
