Is it possible to make a script to change the little icon of the chat window in the taskbar to something different when the user you are chatting with is typing a message?

For example a different colour little man with a speech bubble? Or the speech bubble has dots in it?

Something easy to see would be good...

I noticed this has been asked before, and it is apparently quite possible, but no script was made/ released for it.

There was also some debate over its usefulness... NOTE: I dont use tabs, so there would be no confusion as to which user is typing, unlike if tabs were used.

Any idea's anyone?

Thanks,
Nick.
