When using the pop-out window for the Chatroom, whenever a new person joins the pop-out stops displaying new messages. I hear the notification for new messages, but nothing shows up. If I open the chat window in the main browser (using the tool bar at the bottom), I can see the messages I missed.
Closing the pop-out and re-opening it works until someone else joins the room.
