TouchEvent.TOUCH_MOVE not fired on MS Surface - actionscript-3

Question

I'm developing an AIR app prototype on Surface, and I'm noticing that TouchEvent.TOUCH_MOVE is not fired as expected....
I've built a quick debug application:
private var tf:TextField;
public function init():void{
trace("init");
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
tf = new TextField();
tf.multiline = true;
tf.width = 800;
tf.height = 2000;
this.stage.addChild(tf);
tf.text = "Test";
var touch:Sprite = new Sprite;
touch.graphics.beginFill(0xFFFF00,0.3);
touch.graphics.drawRect(0,0,800,200);
touch.graphics.endFill();
this.stage.addChild(touch);
touch.addEventListener(TouchEvent.TOUCH_BEGIN, updateTF);
touch.addEventListener(TouchEvent.TOUCH_END, updateTF);
touch.addEventListener(TouchEvent.TOUCH_MOVE, updateTF);
touch.addEventListener(TouchEvent.TOUCH_OVER, updateTF);
touch.addEventListener(TouchEvent.TOUCH_TAP, updateTF);
touch.addEventListener(TouchEvent.TOUCH_ROLL_OUT, updateTF);
touch.addEventListener(TouchEvent.TOUCH_ROLL_OVER, updateTF);
}
private function updateTF(event:TouchEvent):void
{
trace(event);
tf.appendText("\n event:" + event);
}
...and it confirms me no TouchEvent.TOUCH_MOVE is being fired.
What could be the issue?
Thank you

So, I didn't solve the issue but I found the explication and a workaround.
This is bug on AIR 3.8 on Windows 8.
Just install a previous version of AIR.
Hope it helps someone :)

You can use MouseEvents instead of touch events for Microsoft Surface. Because adobe not yet released for Microsoft Surface touch device(see adobe labs).
Normally all touch events fall back to mouse events so you can try with Mouse-events. It works well for me . But not sure about Mouse Move event but it works for touch begin and touch end events to mousedown and mouseup events.
