ActionScript 1/2 :: Click Broadcast - Placing Artwork And Contents On Timeline

I'm making some elearning courses and we are trying to combine semi-automation with the ability to place artwork and content on the timeline. Basically we have a series of small tasks -- read this, click this button, see the result, and so on. We have a "highlight" area component that indicates the area a user is to click. Currently that component dispatches and event from the instance when it is clicked and the main timeline is listening for the event and then moves them ahead to the next task when they have clicked properly.

So the following code:
myClickAreaInstance.addEventListener("clicked",handleClick)
And the handleClick function and removing the listener all has to be handled on the timeline. And for a given task there might be an intro animation and the click area component might not come in until the end. So where to put that code and how to automate it becomes tricky. So I first dug up AsBroadcaster and could use it sort of like Mouse or Key classes.

AsBroadcaster.initialize(ClickArea)
ClickArea.addListener(this);
function clicked(obj){
//handle click broadcast
[Code] .....

Would it be better to us AsBroadcaster or EventDispatcher?
