I was so hoping someone could help me.
I saw a question like this a few weeks ago.  If I'm asking something that's
already been answered or is in a FAQ or something, I'm really sorry.

None of my Java applications have frame decorations when run under Linux.
The exact same program will look "proper" on Win98SE, NT, and XP.
This affects *all* my Java applications - including 3rd-party and JDK demos.
And it doesn't matter if the application is AWT or Swing based.
It doesn't matter if I run the program on the console, from telnet, or
through xterm.
I never had this problem with previous versions of Java or Linux.

Here are all the specifics I can think of ...
RH7.x, kernel 2.4.20-24.8
GNOME desktop
(I don't use Java through gcc.)

These are the packages that are installed:

Even this simple little program can demonstrate my problem ...
If I compile/run this program on Linix, I get nothing but an immobile gray
box with my message in it.
If I compile/run this under Windows, all looks "normal."

import java.awt.*;
import javax.swing.*;
public class noframe extends JFrame
{
   public noframe ( String title ) { super( title ); }

   public static void main ( String[] args )
       throws ClassNotFoundException,
              InstantiationException,
              IllegalAccessException,
              UnsupportedLookAndFeelException
   {
       noframe noframe1 = new noframe( "You'll Never See This" );
       noframe1.setSize( 300, 300 );
       noframe1.setLocation( 100, 100 );
       JLabel label1 = new JLabel( "This shows fine", JLabel.CENTER );
       noframe1.getContentPane().add( label1 );
       noframe1.setVisible( true );
   }
}
