>I have this problem everyday when using FireFox. I have switched back to IE for the UT. This isn't a UT problem for me however as many websites have caused the same thing in FF that don't in IE. I also noticed several hundred posts on the FF forum about the "Waiting..." issue but not substantive solution. UT in IE are working great for me today.

Interesting. Unfortunately, here I can not use IE at all (due to login problems) - but I may try to use UT in IE Tab and see if this would help.
