Hi,

I've cobbled together some code using NetBeans 6.1. A reduced version
of the code is below. When I run it, it sometimes shoes the menu bar
and sometimes doesn't. Any idea why? I'm also having some difficulty
with action listened, but I'll deal with that later.

Regards,
JNY

public class Main extends JFrame{

    public static void main(String[] args)
    {

    final JFrame frmMainFrame = new JFrame("2D-CA Viewer-ImportData");
    frmMainFrame.setLayout(new GridLayout(5, 5));
    JPanel pnlCAPanel = new JPanel(new FlowLayout());
    frmMainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frmMainFrame.setSize(500, 500);
    frmMainFrame.setVisible(true);

    JMenuBar menuBar = new JMenuBar();
    JMenu file = new JMenu("File");
    menuBar.add(file);
    JMenuItem getData = new JMenuItem("Get Data");
    file.add(getData);
    frmMainFrame.add(menuBar);
    frmMainFrame.setJMenuBar(menuBar);

}

}
