Hello there!

    I am having difficulties figuring out how to let an object send ddifferent
messages to other objects at the same time. What I want is something like a
popUpList so that when the mouse goes down, the button send a message pop: to
the popUpList and when the mouse goes up, the popUpList send a setTitle: to the
button and at the same time notify another object that the button has changed
its title.   What I can think of is that I can rewrite setTitle: so that it 
also notifies the object I want to notify. I think it should work though I have
not tried it yet.  I feel there should be better way to set mutiple targets for
an object.  Please let me know if you have better ideas.

  Thanks in advance.
