After setting stage.transform.matrix3d, mouse event localX/Y stageX/Y do not work

Question

Hello
Because i need to do 3d transformation on the whole stage, i set the stage transfromation.matrix3d.
I made one test application and find that mouse event doesn't work properly.
In my application, i simply add a sprite containing red circle and test the functions.
Besides, i scale the stage along x-axis half using stage.transform.matrix3D
The problem is that when i click on my red circle, the e.localX/Y and e.stageX/Y are all zeros.
But if i click on places rather than my red circle be, the e.localX/Y and e.stageX/Y work fine.
Here is my code.
public function init():void{
                              var m:Matrix3D= new Matrix3D();
                              m.copyRowFrom(0,new Vector3D(0.5,0,0,0));
                              m.copyRowFrom(1,new Vector3D(0,1,0,0));
                              m.copyRowFrom(2,new Vector3D(0,0,1,0));
                              m.copyRowFrom(3,new Vector3D(0,0,0,1));
                              stage.transform.matrix3D = m;
                              s.graphics.beginFill(0xff0000);
                              s.graphics.drawCircle(0,0,50);
                              s.graphics.endFill();
                              addChild(s);
                              s.x = (stage.stageWidth)/2;
                              s.y = (stage.stageHeight)/2;
                              s.z = 0;
                              stage.addEventListener(MouseEvent.CLICK, onStageClick);
private function onStageClick(e:MouseEvent):void{      
                              trace("global" + e.stageX + " " + e.stageY);
                              trace("local" + e.localX + " " + e.localY);

1. In the code, I think it should change the value of the "player" so that it reflects the right turn. E.g. after the user press the mouse, the player should be changed to "computer" and after the computer goes, the player should be changed to "you". Otherwise, the player stays the same value and the program will only print out one symbol, which in this case is "O".
2. To make the previous moves stay, the code has to get some way to remember the moves. So before the repaint, the program will record the context for the next paint method.
