_root.attachMovie("preloader", "preloader", _root.getNextHighestDepth(), {_x:Stage.width / 2, _y:Stage.height / 2});
preloader._x -= preloader._width / 2;

_level1.stop();
_root.onEnterFrame = function () {
    var percent:Number = Math.ceil((_level1.getBytesLoaded()/_level1.getBytesTotal()) * 100);
    this.preloader.gotoAndStop(percent);
	this.preloader.progress_string.text = percent + "%";
    if (percent > 99) {
		this.preloader.removeMovieClip();
        delete this.onEnterFrame;
		_level1.gotoAndPlay(2);
