I don’t suppose you’re using Windows Vista are you??? (God forbid!!!)
BTW, you didn’t answer Martin’s question. If we don’t know what sort of error message you get when you leave the chatrooms, then we can’t begin to resolve your issue.
Of course I’m making the assumption that you aren’t typing a load of obscenities into the chatroom or persistently scrolling …. you wouldn’t be one of those naughty users that get regularly booted
would you???
