Java SE (Java Platform, Standard Edition)

Hello all hope you guys can help. I figured out how to change the cursor in my Java application by doing the following:

       
        java.net.URL cursorImgURL = ldr.getResource("ball2.png");
        ImageIcon cursorImg = new ImageIcon(cursorImgURL);

        //Set Cursor for frame
        Point point=new Point(0,0);
        Cursor c=Toolkit.getDefaultToolkit().createCustomCursor(cursorImg.getImage(), point,"cursor");
        frame.setCursor(c);

This code sets the cursor of the frame on a Mac to the following image: [What cursor looks like on Mac OS X|http://doodletype.com/ball2.png]

However when on Windows it seems to stretch the image like this: [What cursor looks like on Windows|http://doodletype.com/ball_windows.png]

I was wondering if anyone could tell me why it is stretching the cursor and how I could correct this. I want it to display exactly like it looks on Mac OS X (the first image) and not stretched like the second image. Any help would be great. Thanks :)

If you want to try it out here is a little program to display the cursor: You can download the cursor image here

package cursor;

import java.io.*;
import java.awt.*;
import javax.swing.*;


public class Main extends JFrame {

    ImageIcon cursorImg = new ImageIcon("");
    Cursor c;
    public static void main(String[] args) {
        new Main();
    }

    public Main() {
        JTextField field = new JTextField("");
        field.setText(JOptionPane.showInputDialog(this,"Enter the full filepath for the cursor image","Cursor image?",JOptionPane.QUESTION_MESSAGE));
        if(!field.getText().equals("")) {
            cursorImg = new ImageIcon(field.getText());
        }
        else {
            System.exit(0);
        }

        File image = new File(field.getText());
        if(!image.exists()) {
            JOptionPane.showMessageDialog(this, "Image file does not exist, please check the file path and try again.","Warning",JOptionPane.WARNING_MESSAGE);
            System.exit(0);
        }


        //Create cursor
        Point point=new Point(0,0);
        c=Toolkit.getDefaultToolkit().createCustomCursor(cursorImg.getImage(),point,"cursor");

        setCursor(c);
        setSize(500,500);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

}
