I think she is looking to have the icon bounce once when an application creates an error, or needs attention.
I'm not sure on Panther, but on Jaguar this is what i did for such a thing:
Go to your Speech preferences.
Select the "Spoken User Interface"
Check the box "Anounce when a program needs your attention".
This does NOT need to have Speech activated, it works on it's own.
What happens now, when a program runs in background while you are doing something else, and it needs your attention it will come up with an allert (you can random put an allert message in).
Note: it does NOT work when an application stopped responding.
A force quit from the contextual menu in the dock is the only thing that helps (or through the shortcuts).
