Java Robot does not work in the game, does anyone know if there is a way?

Question

I recently made a bot for a game and had a problem that had occurred to me before. The code runs out of the game but when I click on the game and press to start, only the Mousemove(robot class, java ) works.

At the time, the resolution was just to run the eclipse as administrator and everything worked. I now made for another game and in this technique does not work.

I’ve isolated this code to test :

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;

public class Clique {

    public static void main(String[] args) 
    {
        Robot auto;
         try {
                auto=new Robot();
                System.out.println("delay");
                auto.delay(5000);
                auto.mousePress(InputEvent.BUTTON1_DOWN_MASK);
                auto.delay(100);
                auto.mouseRelease(InputEvent.BUTTON1_DOWN_MASK);
            } catch (AWTException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }

}

And even a simple click doesn’t work( out of the game works ), someone knows what might be occurring?

OBS : this is a PC game, a MMORPG more specifically.
