Building a Jframe

Question

Hi ,
I am having a wierd problem with one of th tutorials onavaiable on this site. It is the Divelog tutorial. I am running java 1.4.1_02 on windows 2000. When I run the tutorial on this machine it hangs at the point when it is supposed to build the Jframe. (I figured this out by placing some system.println commands in there) Whe one of my office mates run it on the same type of machine it works. I know this is a long shoty, but any advice or ideas???
Thanks,
Bernie

ok, but like I said it works on other machines with similar configs.
package divelog;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class DiveLog
{ //Opens DiveLog class
private JTabbedPane tabbedPane;
private JFrame dlframe;
public DiveLog()
{ //Opens DiveLog constructor
//Create a frame object to add the application
//GUI components to.
     System.out.println("creating frame");
dlframe = new JFrame();
System.out.println("setting title");
          dlframe.setTitle("A Java Technology Dive Log");
// Closes from title bar
//and from menu
     System.out.println("adding window listener");
dlframe.addWindowListener(new WindowAdapter()
{ // Opens addWindowListener method
public void windowClosing(WindowEvent e)
{ // Opens windowClosing method
System.exit(0);
} // Closes windowClosing method
}); // Closes addWindowListener method
// Tabbed pane with panels for Jcomponents
     System.out.println("creating tabbedpane");
tabbedPane = new JTabbedPane(SwingConstants.LEFT);
tabbedPane.setBackground(Color.blue);
tabbedPane.setForeground(Color.white);
// Calls a method that adds individual tabs to the
//tabbedpane object.
populateTabbedPane();
//Calls the method that builds the menu
buildMenu();
} // Ends class constructor

} //Ends populateTabbedPane method
private void buildMenu()

          dlframe.getContentPane().add(tabbedPane);
          System.out.println("packing");
dlframe.pack();
dlframe.setSize(765, 690);
     dlframe.setLocation(200,200);
dlframe.setBackground(Color.white);
dlframe.setVisible(true);
// main method and entry point for app
