    Default mouse getX and getY are off?

    I created a MouseMotionListener to detect when then mouse moves over a menu item. I noticed that the getX() and getY() are off a little bit. It seems like the Y is off by 20pixels or so, and the X is off by about 5-6. Here is my mouse code:
    import java.awt.event.MouseMotionListener;
    import java.awt.event.MouseEvent;
     
    public class mouseMotion implements MouseMotionListener {
    	public void mouseMoved(MouseEvent e){
    		if (e.getX() >= 608 && e.getX() <= 640 && e.getY() <= 32) {
    			System.out.println("test");
    		}
    	}
    	public void mouseDragged(MouseEvent e){}
    }

    The image is 32x32pixels and is painted at (608,0), Which is why I assumed that I should check if the mouse is in (608-640,0-32)

    I set my JFrame's size with the following code to prevent this bug, but it seems that it's back...

    f.getContentPane().setPreferredSize(new Dimension(640,480));
    f.add(gui);
    f.addKeyListener(kb);
    f.addMouseListener(m1);
    f.addMouseMotionListener(m2);
    f.pack();
    f.setVisible(true);

    Thank you so much! Should I also use keyListener on the JPanel?
