Hello Ladies and Sirs,

I want build glass effect on Chrome if i move chrome and glass effect should stay at masked background like Windows Vista and 7 effect masked background.

Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
						xmlns:mx="library://ns.adobe.com/flex/mx"
						creationComplete="appcompleteHandler(event)" layout="absolute"
						showFlexChrome="false">
	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			
			[Embed(source="vista-glass.png")]
			private var glass_bg:Class;
			//private var screen:Screen;
			
			protected function appcompleteHandler(event:FlexEvent):void
			{
				var bg:Sprite = new Sprite();
				var bmp:Bitmap = new glass_bg();
				bg.addChild(bmp);
				bg.x = Screen.screens.x;
				bg.y = Screen.screens.y;
				
				bg.width = Capabilities.screenResolutionX;
				bg.height = Capabilities.screenResolutionY;
				bg.blendMode = BlendMode.ALPHA;
				canvas.blendMode = BlendMode.LAYER;
				canvas.mask = bg;
			}
			
			protected function canvas1_mouseDownHandler(event:MouseEvent):void
			{
				stage.nativeWindow.startMove();
			}
			
		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- Platzieren Sie nichtvisuelle Elemente (z.*B. Dienste, Wertobjekte) hier -->
	</fx:Declarations>
	<mx:Canvas id="canvas" left="10" right="10" top="10" bottom="10" backgroundAlpha="0.5"
			   backgroundColor="#A6A6A6" mouseDown="canvas1_mouseDownHandler(event)">
	</mx:Canvas>
</mx:WindowedApplication>
And XML:
transparent is true.
SystemChrome is none.
And embedded image.
