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.

>I was just about to post a similar thread. Several times in last few days I got the problem of UT not responding. Usually I closed UT in such cases and came back in 10-15 minutes when the problem cured by itself.
