Bug on friend chat window?

I had the window open, then I clicked restart to change chars and the window didn't close as it used to.. So, when I tried to talk through it it DCd me from the server. Happened once, I'll try to make it happen again..

Same thing happened to me last night, so not just your game.

Yeah, and now I tried logging to another char with the window open, and the game crashed.. lol..
