Resizing issues

programming flash

Hello Action Scripter better then thou,

I’m running a function that adjust the position of a movie “index_mc” to the bottom left of the browser. Then I have another script that moves this “index_mc” into the center but when the browser is resized it goes back to the bottom left. How should the if statement look so that it stays in the center even if the browser is resized?

here is a sample of my script

 var stageResizeListener:Object = new Object();
stageResizeListener.onResize = function() {

index_mc = (Stage.width+-750)/2;

};
Stage.align = "TL";
Stage.scaleMode = "noScale";
Stage.addListener(stageResizeListener);
Stage.addListener(sizeListener);
