Hi Su
Sorry but the only chat room that plugs into the forum software is the one we have. Actually that is a bit of a lie because there is an IRC chat room but when i tried that it either crashed or hung my pc. So the one we have is the best that is available. I know it is not very good.
I have just upgraded to the latest version but not sure if that will fix the problem you are seeing...
Thanks
Michael
PS will see if there is a better one out there...
