How can you disable mouse-wheel scroll in TextArea component - AS3.0

Recently had a requirement to disable mouseWheel scroll in textArea component in Flash CS4.0 using AS3.0.

It does not get disable by using below statement :

myTxt.textField.mouseWheelEnabled = false;

You also need to stop propagation of that event.

myTxt.addEventListener(MouseEvent.MOUSE_WHEEL, disableMouseHandler, true);

function disableMouseHandler(event:MouseEvent):void {

event.stopPropagation();

}

You need to add both the above codes together to disable mouseWheel.
