JSwing code errors with mouse over

Question

Basically this code is set up to change the background of Jtextfield when the Jtextfield contains the cursor. But, it seems that i have issues because it only works if the cursor is in the upper corner of my window frame. I think it has something to do with my hiearchy, but am unsure how to fix.. help will greatly be apreciated.
its in two seperate class files by the way.
import javax.swing.*;
public class yahtzeeTest
      public static void main(String[] args)
     tes menu=new yahtzee();
     JFrame appFrame=new JFrame();
     appFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     appFrame.setContentPane(menu);
     appFrame.pack();
     appFrame.show();     
// seperate file
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
public class testeld extends JPanel implements ActionListener, MouseMotionListener
     private static int      panelW = 400,
                              panelH=350;
     JTextField tf[]=new JTextField[2];
       Point cursor;
     public testeld()
     setPreferredSize(new Dimension(panelW, panelH));
     setLayout(null);
     addMouseMotionListener(this);
     setBackground(Color.red);
          for(int i=0; i<2;i++)
          tf=new JTextField( "",i);
          tf[i].setBounds(200, (30+(26*i)), 30,20);
          tf[i].setEnabled(false);
          add(tf[i]);
          tf[i].addActionListener(this);     
     public void actionPerformed(ActionEvent ae)
          Object src = ae.getSource();
     public void paintComponent(Graphics g)
          super.paintComponent(g);
          Graphics2D g2=(Graphics2D)g;
     public void mouseMoved(MouseEvent me)
     int x=me.getX();
     int y=me.getY();
     this.cursor =new Point(x, y);     
     for(int i=0; i<tf.length; i++)
          if(tf[i].contains(cursor))
               tf[i].setBackground(Color.yellow);
          else
               tf[i].setBackground(Color.white);
     public void mouseDragged(MouseEvent me){}

Answer 1

1) Swing related questions should be posted in the Swing forum.
2) I would use the mouseEntered, mouseExited events to set/reset the background.
3) Why did you overried paintComponent()
