Accessing mc farthest from z

programming flash
1

Hello.

I’ve loaded 5+ instanced movie clips, each of which play 48 frames simultaneously once and then stop (mc1,mc2,…mc5)

These mcs were added via addChild.

private function setupMenuA():void {
  addChild(mc1);
  
  //properties
  mc1.blendMode="screen";

  // code to play mc1 once and then stop
  mc1.addFrameScript(0, function() {mc1.stop();});
  mc1.addFrameScript(47, function() {mc1.stop();})

}

// call to play menu A
private function playMenuA(event:Event):void {
  // go to first frame
  mc1.gotoAndPlay(0);

  mc1.play();

}

The problem is after completing the animations-any further MouseEvents only see mc5 and I cannot access mc1-mc4.

I’m stuck and any help would be appreciated.
Thanks.
