MouseEvent not firing on DisplayObject click in AS only project in Flash Builder 4

Question

Hello,
I'm having difficulty getting MouseEvents to fire in an ActionScript only project. It doesn't make any sense to me. My code is below and this object is the top most object on the stage.
var click:Sprite = new Sprite();
click.name = 'clickLayer';
click.mouseEnabled = true;
click.addEventListener(MouseEvent.CLICK, mouseClickHandler);
addChild(click);
function mouseClickHandler(e:MouseEvent):void{
trace('click');
var url:String = loaderInfo.parameters.clickTag;
navigateToURL(new URLRequest(url), '_blank');
My class extends Sprite.
Everything else works fine. Something I found strange is that TextFields will fire MouseEvents when clicked if I add the EventListener, but not DisplayObjects.
Thanks for your help.

I just made the width & height the width & height of the container (Sprite), but still nothing.
I also tried adding a "container" sprite to the main stage, and adding everything to that sprite - but that sprite won't instantiate and doesn't show on the stage, meaning anything added to that sprite doesn't show either.\
Also: I've tried adding MouseEvent listeners to every display object I add to the stage and nothing will fire MouseEvents except TextFields.
