Flash Liquid Layout - Top Left Corner

This code is for top left aligning an object inside a centered fullscreen Flash movie. Took me a while to figure this out, but here's the code:

Stage.align = "T";
Stage.scaleMode = "noScale";

originalStage = Stage.width;

sizeListener = new Object();
sizeListener.onResize = function() {
myObject._x = myObject._x-((Stage.width-originalStage)/2);
originalStage = Stage.width;
};
Stage.addListener(sizeListener);
