OK, but if you decide different, note that you can point
a javax.jnlp.FileOpenService to the current directory by
feeding it a path hint of ".".  Using JNLP services for 
things like that, would allow this application to be 
offered in a 'sandboxed' form.

You are welcome.  I have an interest in looking into
JWS apps. in general, to get a sense for how close 
they come to being fully 'sandbox'able.

A JWindow?  Please try to be specific*, so we are all
sure we are 'on the same page'.  A quick test** in Java
6 suggests the default layout for JWindow is BorderLayout
as well.  

Without specifying a layout constraint for an added 
Component, the default is BorderLayout.CENTER.

That is the window showing the Uni. site we are 
referring too, right?

* Hey! You know what I was saying about 'specific'?
Now I recheck it I realise that is specifically *not* 
a JWindow - looks like a JFrame, am I right?  OK - 
all the above  is same for JFrame**, but please 
refrain from using generic terms like 'window'.

Now - I still don't think I have quite managed to 
communicate what I am seeing, but since 'a picture
paints a thousand words', I'll give you 'two thousand'..

Besides the odd problem of the web page appearing 
and disappearing according to the width of stretched
main JFrame, the JTables of the JFrame could use 
adjusting.  Those JTables could do with stretching 
left to right as the JFrame increases width.  I 
suspect they went into the WEST of one of the 
BorderLayouts?

** Little example
<sscce>
import java.awt.*;
import javax.swing.*;

class DefaultLayoutManager {

  static String[] constraint =
  {
    BorderLayout.NORTH,
    BorderLayout.EAST,
    BorderLayout.WEST,
    BorderLayout.SOUTH,
    BorderLayout.CENTER
  };

  public static void main(String[] args) {
    JFrame root = new JFrame();
    System.out.println( root.getLayout() );

    for (int ii=0; ii<constraint.length; ii++ ) {
      root.add(
        new JButton(constraint[ii]),
        constraint[ii] );
    }

    //check where the component goes, by default
    root.add(new JLabel("Default") );

    root.pack();
    root.setVisible(true);
  }
}
</sscce>
