I thought the inputEndEditing message was sent whenever the input field 
loses focus. Seems like you should be getting that message right before 
the second field triggers the focusIn message. Is that not happening?

You could insert a temporary "put" statement at the beginning of the 
handler to see if it is triggering, and watch for it in Console. Maybe 
something is aborting the handler before it finishes executing.
