Movieclip resizes outside browser boundaries...[AS2, FL8/9, CS3]

1

hello all,

the following code makes the box come up correctly, however when i resize the browser, it seems to calculate based on the previous stage size not the current one.

if you open the swf and make the browser very wide and not so tall, it runs off the top and bottom. can anyone mod the math/code to keep the proportions the same and always stay in the browser?

thanks for any help

#include "mc_tween2.as"
Stage.align = "TL";
Stage.scaleMode = "noScale";
 
var sw:Number = Stage.width;
var sh:Number = Stage.height;
 
mcDvpane._width = sw-100;
mcDvpane._height = mcDvpane._width*.618;
mcDvpane._x = sw/2;
mcDvpane._y = sh/2;
 
var stageListner:Object = new Object();
stageListner.onResize = function() {
 mcDvpane.tween("_width",Stage.width-100,0.75,"easeOutQuart");
 mcDvpane.tween("_height",(Stage.width-100)*.618,0.75,"easeOutQuart");
 mcDvpane.tween("_x",Stage.width/2,0.75,"easeOutQuart");
 mcDvpane.tween("_y",Stage.height/2,0.75,"easeOutQuart");
};
 
Stage.addListener(stageListner);
