External SWF does not play - stays on first frame

My external SWF file plays fine until I add the remove on mouse event (SWF file loops until a button is clicked). When removeSwf is add the SWF stays on the first frame.

Any help would be wonderful - Thank you

var request:URLRequest = new URLRequest("PicLoop3working.swf");

var loader:Loader = new Loader()

loader.load(request);

addChild(loader);

addEventListener(MouseEvent.CLICK, removeSWF);

function removeSWF(e:MouseEvent):void{

removeChild(loader);

}
