Gill,
I did find myself in this situation and yes it is a bit of a pain.
The only way to get around it is to close all your internet explorer windows and then login again. It appears that even if you have one IE window open, DChat's java classes use that and think you are connected still. I have been meaning to ask the support people of DChat but never got around it.
I will do though and let you know shortly.
Warm regards
Nikos
