I thought the child of the parent (main application) would be
up the chain. The child has to listen and react to the event dispatched by the
main application.
"I've got a parent application with a 'delete'
button. When it's clicked, I want to set a flag in a child swf, which is loaded
via SWF loader.

You are misunderstanding how listeners work.
You add the listener to the component that *dispatches*
the event, and have it call a method where you want the action to take place.
"parent" just goes up one
component. The surest way to do this is to use
Application.application.addEventListener(). A bubbling event will hot help
you going
in this direction (down to the child)

Hi Steve,
But I need the child swf to react, not the parent. So I think the
listener has to be in the child, not the parent.
