I try to be synthetic:

I'm dispatching an event from a MovieClip (customized symbol in library) this way:

public function _onMouseDown(e:MouseEvent){
            var obj = {targetClips:["tondo"],functionString:"testFF"};
            dispatchEvent(new BridgeEvent(BridgeEvent.BRIDGE_DATA,obj));
        }

The BridgeEvent class is the following:

package events {
    import flash.events.EventDispatcher;
    import flash.events.Event;

    public class BridgeEvent extends Event {
        public static const BRIDGE_DATA:String = "BridgeData";
        public var data:*;

        public function BridgeEvent(type:String, data:*) {
            this.data = data;
            super(type, true);
        }
    }
}

The document class listens to the event this way:

addEventListener(BridgeEvent.BRIDGE_DATA,eventSwitcher);

In eventSwitcher method I have a simple trace("received").

What happens: when I click the MovieClip the trace action gets duplicated and the output window writes many "received" (even if the click is only one).

What happens? How do I prevent this behaviour? What is causing this?

Any help is appreciated.

[SOLVED] I'm sorry, you will not believe this. A colleague, to make me a joke, converted the MOUSE_DOWN handler to MOUSE_OVER.
