Hi guys,  
I’ve a preload bar in my movieclip that i add on the stage for every thumb.  
With this code only the last preload bar does the preload…the others don’t do anything…Here the code:

```auto
function testMovieClip():void{
    for (var i:Number = 0; i < my_total; i++){
        var thumb_url = my_images*.@ANTEPRIME;
        var thumb_loader:Loader = new Loader();
        thumb_loader.load(new URLRequest(thumb_url));
        MainMovie = new thumbnailholder();
        MainMovie.x = (MainMovie.width + 70)*x_counter;
        MainMovie.y = (MainMovie.height + 70)*y_counter;
        if (x_counter+1 < columns){
            x_counter++;
        } else {
            x_counter = 0;
            y_counter++;
        }
        mainCont.addChild(MainMovie);
        MainMovie.imgMain.addChild(thumb_loader);
    }
    thumb_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, thumbProg);
}

function thumbProg(e:ProgressEvent)
{
    var percnt:Number = e.bytesLoaded/e.bytesTotal;
    MainMovie.prelBar.width = Math.ceil(percnt*100);
}

```

I also try to insert the ProgressEvent.PROGRESS listener into the FLASH structure…but i’ve the same result…
