Re: bouncing

 when you just used the addMouseListener(), you were actually registering 
the MouseListener with the Applet class.  Then, you add the Playpen on 
top of the Applet.  This means that any mouse clicks that occur in your 
applet are actually being sent to the Playpen, which "doesn't care" about 
them. 

 when you used the myPlaypen.addMouseListener(), you were registering the 
MouseListener with the Playpen, and suddenly, the Playpen starting 
"caring" about the mouse clicks.
