Mouse Event Blocked?

I know this is simple, but dangit…

container.addChild(game); //a sprite contaier
container.addChild(gameFrame); //a mc instance from the library

Later on I then do:

question = new Question(questionNum);
question.btnTrue.addEventListener(MouseEvent.CLICK, questionAnsweredTrue);
game.addChild(question);

However the ‘gameFrame’ above ‘game’ is preventing clicks from being intercepted by the button within the question clip.

I think it’s a propagation thing, but since I have no listeners on the gameFrame I wasn’t sure.
