Thanks! It works indeed, except that the relaunched application does
not display at front of other windows. It is buried under many other
windows. How do I bring it to front?
BTW what is this processIdentifier thing intended for? Am I meant to
check this id in the main app, when it starts, and wait until the
older app dies?
