[2.0.4] doesn't drag and drop control on MAC OSX --- to be checked

[Huy vu]

I use Sikuli API on JAVA to test app on MAC and I face a problem Sikuli doesn't drag and drop control (Sikuli only move from imageA to image B)

Here is my script:

import org.testng.annotations.Test;
import org.sikuli.script.Screen;
import org.sikuli.script.Match;

public class test {
       @Test
 public void testcase(){
  Screen s = new Screen();
  Match src = s.find( "\ws\imageA.png");
  Match des= s.find("\ws\imageB.png");
  s.dragDrop(src, des);
       }

Note: It's work fine on win but on MAC OSX, I just saw mouse move from imageA to imageB.

Please let me know if anyone has resolved this issue.
