Why Matrix does this?

programming flash

I want to be able to drag and drop the movieclip and dynamically skew based on the mouse position but. When I click the movie clip it jumps to top left corner, and I can’t drag and drop the mc… Why is this?


import flash.geom.Matrix;
import flash.events.MouseEvent;
import flash.sampler.NewObjectSample;


//shadow matrix 


circ.addEventListener(MouseEvent.MOUSE_DOWN, drag)
circ.addEventListener(MouseEvent.MOUSE_UP, drop)


function drop(event:MouseEvent):void{
	circ.stopDrag();
	stage.removeEventListener(Event.ENTER_FRAME, skewer)
}


function drag(event:MouseEvent):void{
	circ.startDrag();
	stage.addEventListener(Event.ENTER_FRAME, skewer)
	 //circ.transform.matrix = sm;
}


function skewer(e:Event):void{
	
	circ.scaleX = 1 + Math.abs((550 - mouseX)/550);
	var sm:Matrix = new Matrix();
	
	//a = x scale / b = y skew / c = x skew / d = y scale / tx = x translation ty = y	
	sm.b = 1 + Math.abs((550 - mouseX)/550);
	circ.transform.matrix  = sm;
	    	
}

Thanks
