Resizing issues Continued

Okay since 50 people read my last post to no avail. I realized I probably haven’t been asking the right questions. What I think I need to know is how to write a script that stops my “bottom left of the browser” function which is:

Stage.align = "TL";
Stage.scaleMode = "noScale";
var stageResizeListener:Object = new Object();
stageResizeListener.onResize = function() {
    index_mc._y = Stage.height-audio_onoff_mc._height;
};
Stage.addListener(sizeListener);

Then I have another action that moves the _y coordinate of the “index_mc”.

So… long story short, How would I write a listener that stops the “bottom left of the browser” function when say the ._y coordinate is at 330?
