Why does this Event Listener stop listening?

I have built a flash movie that is located here:

http://faithkealadesign.com/get_files/blueflairphotography/index.html

For some reason after the timeline plays through completly (after the "headshots and potfolios" slide) the listener on the "child and family portraits" button stops listening or responding. Why is that? All the other event listeners are behaving themselves except this one?

Any advice?

Here is the actionscript:

McChild.addEventListener(MouseEvent.MOUSE_OVER, fl_MouseOverHandler);

function fl_MouseOverHandler(event:MouseEvent):void
{
    gotoAndStop(65);
    trace("Moused over");

    gotoAndPlay(71);
    trace("Moused out");
}
