You can learn the answers these questions by reading another part of my
previous followup that you did not quote in your reply.  Here is that
part again:

  You are likely seeing different redrawing results from pack() and
  hiding-and-showing because one ends up invoking update while the other
  ends up invoking paint.  See
                                                                                
  http://java.sun.com/products/jfc/tsc/articles/painting/index.html#awt
                                                                                
  for a description of "Painting in the AWT".

Over-simplifying:

- When a Java program executes repaint (either directly in code you write
  or in the implementation of standard java methods, such as pack) the
  update method will be called.  Your update method clipped to the size
  of the original image.

- When the windowing system of the computer on which a Java program is
  running determines that a window needs to be repainted, the paint method
  will be called.  Your paint method did not clip to the size of the
  original image.
