       private Keyboard kb;
       private ScreenRegion sr;
       private Mouse mouse;
       private Canvas painter;
       private ScreenRegion rect;

       @BeforeSuite(alwaysRun = true) 
       public void setupSuite() { 

              Settings.setShowActions(false);
           Settings.SlowMotionDelay = 1; 
           Settings.ClickDelay = 0.5;

              s = new Screen();
              sr = new DesktopScreenRegion();
              kb = new DesktopKeyboard();
              mouse = new DesktopMouse();
              painter = new DesktopCanvas(); 
       }

...

private void singleClick(String imagePath) throws FindFailed, 
InterruptedException {

              painter.addCircle(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.display(1);
              mouse.click(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.clear();
       }

       private void doubleClick(String imagePath) throws FindFailed, InterruptedException {

              painter.addCircle(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.display(1);
              mouse.doubleClick(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.clear();
       }

       private void rightClick(String imagePath) throws FindFailed, InterruptedException {

              painter.addCircle(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.display(1);
              mouse.rightClick(sr.find(new ImageTarget(new File(imagePath))).getCenter());
              painter.clear();
       }

imagePath is the image file which passed into the click function.

Thanks.

Hi RaiMan,

Here is the click issue for upload a file to website, you can see the Upload 
button was greyed out, is not clickable.

Suppose to be seen like this:

This has been happening for so many times already, and this time, I am very 
much sure I am using 1.0.1 version of sikuli-java.jar file.

The last one was that I have done it by manually, when I did it manually, I 
always make sure I clicked hard enough to ensure the file is selected.

Thanks.
-Kurt.
