strange problem

[Randall Twede]

i have a JFrame with a border layout with a JPanel containing JRadioButtons in north and a class DrawingArea that extends JPanel in the center. DrawingArea implements MouseListener. mouseReleased() has two lines of code one of which calls repaint(). for some reason it causes a second row of RadioButtons to appear below the first ones. when i override paintComponent() it also creates a second border around the DrawingArea. if i overide paint() instead it erases the original border. it only does this the first time after that it just draws rectangles like it is supposed to. i dont have a clue how this is happening. i implemented all the methods of Mouse Listener and i even implemeted MouseMotionListener also to no avail. here is some of the code.
in Jframe

private JPanel control = new JPanel();
private DrawingArea canvas = new DrawingArea();
    public  ShapeDrawer()
    {
        Container c = getContentPane();
        c.setLayout(new BorderLayout());
        initComponents();
        c.add(control, "North");
        c.add(canvas, "Center");
    }
    public static void main(String args[])
    {
        ShapeDrawer test = new ShapeDrawer();
        test.setSize(400, 400);
        test.setLocation(200, 100);
        test.setVisible(true);
        test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

in DrawingArea

    public DrawingArea()
    {
        setBorder( BorderFactory.createTitledBorder( "Drawing Area" ) );
        addMouseListener(this);
        addMouseMotionListener(this);
    }
    
    public void paint(Graphics g)
    {
        drawRect(g);
        fillRect(g);
        drawOval(g);
        fillOval(g);
    }
    public void mousePressed(java.awt.event.MouseEvent mouseEvent)
    {
        start = mouseEvent.getPoint();
    }
    
    public void mouseReleased(java.awt.event.MouseEvent mouseEvent)
    {
        end = mouseEvent.getPoint();
        repaint();
    }

When you override paintComponent(), be sure to call super.paintComponent(). That ought to fix this problem, actually.
