>All of a sudden (in the middle of a session) the background color of UT messages (not while editing a message, only during viewing) has switched to the default setting. I set it back to the color of my choice, saved my settings, and logged out and logged back into the UT. It is back to the default again. When I go back in and look at my settings, it is back to the default. Is this only happening to me? What is causing this?

Yesterday, I found that the default background color when reading a message was not good. So, I adjusted it. However, this should only affect new accounts. Yours was created before so your previous settings should be carried on. Just let me know by email if you ever encounter a situation like this with the explanation of pattern.
