How to overcome this problem when resizing the SWF file according to browser size?

Hi,

I am resizing the flash (.swf) file accroding to the browser window to fit on any screen resolution. But the problem I am facing now is related to animations which cross the [COLOR=#0000ff]**STAGE **[/COLOR]area. Say, I have an **aeroplane_mc **which starts animating from [COLOR=#0000ff]x[/COLOR]:-200 to [COLOR=#0000ff]x[COLOR=#000000]:[/COLOR][/COLOR]1200 (my stage width=1000 & height=600), the my flash (swf) file gets shrink.

Because of this problem I cannot make any animation which moves out of stage. Please help me in resolving this problem.

The code to resize the window is as below:

var myStage:Stage=this.stage;
myStage.scaleMode=StageScaleMode.NO_SCALE;
myStage.align=StageAlign.TOP_LEFT;

function initialDisplay(event:Event):void{
var swfWidth:int=myStage.stageWidth;
var swfHeight:int=myStage.stageHeight;

Background.width=swfWidth;
Background.height=swfHeight;
 
}

addEventListener(Event.ENTER_FRAME,initialDisplay);

Thanks in advance for any help.
