I just discovered the pop-out chat today. Awesome feature! However, now that I've got the chat situated nicely on another screen, I've noticed that the chat notification blip (that normally plays when I'm either on another tab, or don't have the browser window selected) now plays every single time someone (including me) sends a chat message. Perhaps we need to have the window focus set to the pop-out window, instead of the main window when we have the chat-popped out. Also the chat notification when you have another tab selected doesn't make any sense with the chat popped out, since it would be impossible to have the chat tab selected.
