External SWF Loads before the Preloader - HELP!

Can somebody help with out with this, the external swf loads before the preloader finishes completely. i've attached the code below.


Movie clip loader

var mcLoader:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
mcLoader.addListener(myListener);

myListener.onLoadProgress = function(target_mc, bytesLoaded, bytesTotal) {
extLoader_mc._visible = true;
var pctLoaded = Math.round(bytesLoaded/bytesTotal*100);
extLoader_mc.extLoaderBar_mc._xscale = pctLoaded;
if (bytesLoaded >= bytesTotal) {
extLoader_mc._visible = false;
}
}

when/where are you making your call to load the .swf?

are you testing locally?

have you tried making the container clip you are loading the .swf into _visible = false..then on loadInit() or when the onLoadProgress() is done.. triggers it to be _visible = true;?
