This sequence of events keeps occuring in UT.
I am in the VFP section, reading messages. My reply indicator increments. I use the mailbox icon, and see that the reply in in a different group (C or NT). I click on the message title in the reply display box. The message displays. Everything seems normal to this point.

After reading the other group reply, I click on a previously read message (of the VFP group),in the upper window. At this point I receive a message that the Host (transformation.com) is not responding.

Upon typing the URL to UT including /universa , i am reconnected.

I don't know if this sequence caused the error, or it is coincendental.
