Нет. Типа так

function onOver (e:MouseEvent):void {
	if (cubeScaleX) {
		cubeScaleX.stop();
		cubeScaleY.stop();
	}
	cubeScaleX = new Tween(cube, "scaleX", None.easeNone, 1, 1.5, 10, false);
	cubeScaleY = new Tween(cube, "scaleY", None.easeNone, 1, 1.5, 10, false);
	cube.addEventListener (MouseEvent.MOUSE_OUT, onOut);
}
