Aligning content to bottom of browser

So i’m trying to align a navigation to the bottom of the browser.

and this is whats happening…The NAV clip is aligning to something, but it’s not working right. I want it to be 25 pixels from the bottom at all times, no matter what size the browser is…

Here is the code and the .fla

fscommand("fullscreen", "true");
Stage.scaleMode = "noScale";
var myListener:Object = new Object();
myListener.onResize = function() {
updateLocations = function () {
    NAV._y = Stage.height - 25;
