Conflict between MovieClip & Combobox

Hi all

This is a bit tricky.

I load a movieclip through a swf file with a loader function which has a class attached to it. The class listens to keyboard event, so that when the up and down keyboard arrows are pressed the clip start to play.

Here is the code for the class listening to keyboard event.

public class Supermarket extends MovieClip
{
public function Supermarket()
{

this.addEventListener(Event.ADDED_TO_STAGE,onAddedToStage);
}
//Keyboard Event
private function onAddedToStage(e:Event):void {
stage.addEventListener(KeyboardEvent.KEY_DOWN,keyPressed);
}
private function keyPressed(evt:KeyboardEvent) {

if (evt.keyCode ==Keyboard.UP){
this.nextFrame(); }
else
if (evt.keyCode ==Keyboard.DOWN){
this.prevFrame(); }
}
}

Here is the code for the loader but I think it’s not important

var originalcamLoader:Loader = new Loader();
originalcamLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, gotOriginalCam);
originalcamLoader.load( new URLRequest(“supermarket_AS3.swf”) );
addChild(originalcamLoader);

function gotOriginalCam(e:Event):void
{
originalcamLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, gotOriginalCam);
}

The problem is that I also have a combo box on stage (main timeline). When I click with my mouse on the combobox to choose an item and then use the keyboard, the KEYBOARD listens to the combobox and NOT the movieclip.
How can I override the combobox or move the focus back to the movieclip.

Thanks
