I think this is an important issue.


And did you already try to use "MouseEvent#relatedObject" instead of 
"getObjectsUnderPoint()"?

testcase:
---
<canvas debug="true">
  <view name="V1" width="100" height="100" bgcolor="0xff0000">
    <dragstate name="drag" applied="false"/>
    <handler name="onmousedown">
      this.drag.setAttribute('applied', true);
    </handler>
    <handler name="onmouseup">
      this.drag.setAttribute('applied', false);
    </handler>
  </view>
 
  <view x="110" name="V2" width="100" height="100" bgcolor="0x00ff00">
    <handler name="onmouseover" >
      Debug.write("Drag mouse over this view");
    </handler>
    <passthrough>
      import flash.events.*;
    </passthrough>
    <handler name="oninit" >
      *if ($swf9) {
        this.f = function (e:MouseEvent) {
          Debug.write((e.target.parent cast LzSprite).owner);
          if (e.relatedObject) {
            Debug.write((e.relatedObject.parent cast LzSprite).owner);
          } else {
            Debug.write("no related object")
          }
        }
        this.sprite.clickbutton.addEventListener(MouseEvent.MOUSE_OVER, 
this.f, false);
      }*
    </handler>
  </view>
</canvas>
