Panel isn't expanding with the window

Question

Hey,
I am writing a Sudoku program, and well I haven't really done anything yet. All it does is draw the board (9x9 grid) on a Panel, then the panel is added to the Applet. Thing is, the Applet is set to a 550x550 size, but the Panel doesn't expand with it. It's stuck at the default(?) size. The TextFields (the grid) expand with the window, so only a few are shown on the screen. A screenshot can be found here -> http://i46.tinypic.com/2wnzqtu.png
Here's the code:
package sudoku;
import java.applet.Applet;
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.Panel;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class PlaySudoku extends Applet implements ActionListener
     static final int FRAME_WIDTH  = 550;
     static final int FRAME_HEIGHT = 550;
     static final int BOARD_ROWS    = 9;
     static final int BOARD_COLUMNS = 9;
     static final int BOARD_WIDTH   = 500;
     static final int BOARD_HEIGHT  = 500;
     TextField[][] grid = new TextField[BOARD_ROWS][BOARD_COLUMNS];
     Panel board = new Panel(new GridLayout(BOARD_ROWS, BOARD_COLUMNS));
     public void init()
          this.setLayout(new BorderLayout());
          this.setSize(FRAME_WIDTH, FRAME_HEIGHT);
          for (int i = 0 ; i < BOARD_ROWS ; i++)
               for (int j = 0 ; j < BOARD_COLUMNS ; j++)
                    grid[i][j] = new TextField();
                    board.add(grid[i][j]);
          this.add(board, BorderLayout.CENTER);
     public void actionPerformed(ActionEvent e)

Only just checked the image.
- What OS is that?
- What is the exact (copy/pasted in code tags) HTML used for the applet viewer?
Or perhaps - run this variant of your code and report back.
// <applet code='PlaySudoku' width='650' height='250'></applet>
import java.applet.Applet;
import java.awt.*;
public class PlaySudoku extends Applet
     static final int BOARD_ROWS    = 9;
     static final int BOARD_COLUMNS = 9;
     TextField[][] grid = new TextField[BOARD_ROWS][BOARD_COLUMNS];
     Panel board = new Panel(new GridLayout(BOARD_ROWS, BOARD_COLUMNS));
     public void init()
          this.setLayout(new BorderLayout());
          for (int i = 0 ; i < BOARD_ROWS ; i++)
               for (int j = 0 ; j < BOARD_COLUMNS ; j++)
                    grid[i][j] = new TextField();
                    board.add(grid[i][j]);
          this.add(board, BorderLayout.CENTER);
          // always a good idea
          validate();
          System.out.println("Size: " + getSize());
          System.out.println("os.name: " + System.getProperty("os.name"));
          System.out.println("java.vendor: " + System.getProperty("java.vendor"));
          System.out.println("java.version: " + System.getProperty("java.version"));
          System.out.println("java.vm.version: " + System.getProperty("java.vm.version"));
}Here are the results I'm getting, with no odd sizing artifacts.
