Fulll browser size flash

Hi I am making full browser page, but resize doesnt work well. It looks like the flash took wrong stageWidth and stageHeight at the start... Then it all works but with wrong numbers :(

(when you launch swf in standalone player, it works well - download http://www.frai.cz/www/frai3.swf)

I have resizing done this way:

Code:

---

stage.scaleMode = StageScaleMode.NO_SCALE;
var start_w:Number = stage.stageWidth;
var start_h:Number = stage.stageHeight;
function initThis(obj:MovieClip):void {
 obj["startX"] = obj.x;
 obj["startY"] = obj.y;
}
initThis(obj1_mc);
initThis(obj2_mc);
initThis(obj3_mc);
initThis(pozadi);
import fl.transitions.Tween;
import fl.transitions.easing.*;
function resized(evt:Event):void {
 var dif_x:Number = (stage.stageWidth-start_w)/2;
 var dif_y:Number = (stage.stageHeight-start_h)/2;
 var tw_1:Tween = new Tween(obj1_mc, "x", Regular.easeOut, obj1_mc.x, obj1_mc["startX"]-dif_x, 12, false);
 var tw_2:Tween = new Tween(obj1_mc, "y", Regular.easeOut, obj1_mc.y, obj1_mc["startY"]-dif_y, 12, false);
 var tw_7:Tween = new Tween(pozadi, "x", Regular.easeOut, pozadi.x, pozadi["startX"]-dif_x, 12, false);
 var tw_8:Tween = new Tween(pozadi, "y", Regular.easeOut, pozadi.y, pozadi["startY"]-dif_y, 12, false);
 var tw_3:Tween = new Tween(obj2_mc, "x", Regular.easeOut, obj2_mc.x, obj2_mc["startX"]+dif_x, 12, false);
 var tw_4:Tween = new Tween(obj2_mc, "y", Regular.easeOut, obj2_mc.y, obj2_mc["startY"]+dif_y, 12, false);
 var tw_5:Tween = new Tween(obj3_mc, "x", Regular.easeOut, obj3_mc.x, obj3_mc["startX"]+dif_x, 12, false);
 var tw_6:Tween = new Tween(obj3_mc, "y", Regular.easeOut, obj3_mc.y, obj3_mc["startY"]-dif_y, 12, false);
}
stage.addEventListener(Event.RESIZE,resized);

Can anyone help? - I am not expert :(

are you setting the stage align to , top left ?

Code:

---

stage.align = StageAlign.TOP_LEFT;
