I'm trying to make full flash site dynamically resize in any browser size.

If the browser gets smaller than the site MC should constrain to fit in the browser. (EX: 1440x900) What I have right now works like 98% of the time, but when I switch to a bigger screen size, it screws up and makes the site tiny from left to right (menu, logo, etc.) (Ex:1680x1050)

Does anyone know how to fix that issue??

positionScenesOnStage();
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.addEventListener(Event.RESIZE, handleObjectsOnStage);


private function handleObjectsOnStage(event:Event):void
{
   positionScenesOnStage();
}

private function positionScenesOnStage():void
{
    backgroundMC = new bgMC();
    backgroundMC.x = 0;
    backgroundMC.y = 0;
    backgroundMC.width = stage.stageWidth;
    backgroundMC.height = stage.stageHeight;
    addChild(backgroundMC);

    logo_mc = new LogoMC();
    logo_mc.x = stage.stageWidth - 1420;  
    logo_mc.y = stage.stageHeight - 700;  
    addChild(logo_mc);

    menuContainer = new MenuContainerMC();
    menuContainer.x     = stage.stageWidth - 400;  
    menuContainer.y     = stage.stageHeight - 680;
    addChild(menuContainer);
}
