myListener.onLoad

I am using Flash MX2004Pro, and have come across something that is driving me bonkers.

I have a preloader set up, and it seems to be working correctly, however, once it is done, and the page in question comes up, the image for the preloader is not vanishing, rather it is sitting behind the image, though still visible.

my code is:

var myMCL:MovieClipLoader = new MovieClipLoader();
var myListener bject = new Object();

MyMCL.addListener(myListener);

myListener.onLoadProgress = function (target_mc, loadedBytes, totalBytes) {
_level50._visible = true;
var preloadPercent:Number = Math.round((loadedBytes / totalBytes) * 100);
_level50.preloader.gotoAndStop(preloadPercent);
}

myListener.onLoadComplete = function (target_mc) {
_level50._visible = false;
}


I don't see anything wrong in it, and have another pair of eyes look it over. That person suggested that I change _level50._visible to preloader.swf._visible ... only that doesn't work either. Does anyone have any ideas?
