pop chat box open once new message received

Hi,

Thanks for an excellent chatting module that working flawlessly with every other module. but unfortunately, a basic feature is lacking I guess.

I have a live site & user making complain that they can't notice when they get message in chat box. Is it possible that, chat box will pop the box once new message received? Like you will find it in facebook. So, people have no chance to miss the large box & message.

Please ask me if you need more info.

Thanks a lot
