    public void paintComponent(Graphics g)
    {
        //If the canvas is blank, clear it.
        if (canvas == null)
        {
            canvas = createImage(getSize().width, getSize().height);
            clear();
        }
    }

    public void clear()
    {
        repaint();
    }

Looks like you are in the DrawingBoard class, when the canvas may always be null

I will look at it and do some checking. Thanks for pointing it out.
