SWFloader loads SWF movie within Flex but not when compiled

Question

When I run my app in Flex, SWFLoader loads the SWF okay as a movie clip but as soon as I Export/Release Build, the new app SWF that is generated won't show the movie clip anymore.  If I take another SWF that is an app (not a movie clip) and give it the movie swf name, my compiled app will show the sub app in a frame.  Why would running something within Flex be any different than running a compiled version?
Here is some of the code:
button1 loads the swf.
button2 loads a sound and when the sound is loaded, the sound is played and the swf is played in onSoundLoaded();
public  function onSoundLoaded(event:Event):void{
var localSound:Sound = event.target as Sound;localSound.play();
var clip:MovieClip = MovieClip(swflodr.content);
clip.play();
private  
function button1Handler(event:Event):void {Alert.show("test 1");swflodr.load(
"dog.swf");Alert.show(
"test 2");}
private  
function button2Handler(event:Event):void
var s:Sound = new
Sound();s.addEventListener(Event.COMPLETE, onSoundLoaded);
var  
req:URLRequest = new URLRequest("test.mp3");
s.load(req);
 private function SwfLodrEventHandler(event:Event):void { 
var clip:MovieClip = MovieClip(swflodr.content);clip.gotoAndStop(1);
Alert.show(
"The event loader is ready");}
thanks, Mike

Maybe timing?  The child SWF may not be fully loaded.  Sounds and SWFs are asynchronously loaded.
