You first need to understand that this loading problem of an external image or SWF is a bug in how the removing a child / garbage collector / display list mechanisms are working in AS3 / Flash player and not an issue with the SWF of your product(s).

That’s because when you remove a child in Flash AS3, the reference to that child is still there in parent although you believed it was entirely removed. Here is a simple function that you can use in the future when you load images or SWFs inside an empty movie clip:

function loadResource(resURL) {

var url = resURL;
var request1 = new URLRequest(url);
var loader1 = new Loader();

var mc1 = this.getChildByName(“mc”);
var nc = mc1.numChildren;

if (nc) { var l1 = mc1.getChildAt(0); mc1.removeChild(l1); l1 = null; }

loader1.load(request1); //start loading img/swf
mc1.addChild(loader1);

loader1.contentLoaderInfo.addEventListener(“complete”, this.finished_loading);

}

function finished_loading(e:Event) { trace(“Loading completed.” }

, where mc is the instance name of an empty movie clip from the stage. You can simply call this function with the path string to your external SWFs and images avoiding references duplicates.
