Hello there.
I've had a good look around the forum - and Flash Help has once again not been very helpful.
I'm just trying to have a function triggered when a certain amount of images have loaded. I've tried so many variations (including copying code from here) but it's not working!
Here's what I've got...(excluding the image-loading code).

var mcl:MovieClipLoader = new MovieClipLoader();
var mclListener:Object = new Object();
mclListener.onLoadInit = function(){
imagesLoaded ++;
trace(imagesLoaded);
if (imagesLoaded == 4) {
images.title.start_btn._visible = true;
loader._visible = false;
};
};
mcl.addListener(mclListener);

Is there anything wrong with that? When 4 images have loaded, it's supposed to make the 'start' button visible, but no go so far.
I've tried using 'onLoadComplete' instead, but from some comments on-line it sounds like that might behave a bit unpredictably.
If anyone can help me out, that'd be great.
