Although I do agree that normally you should use spinners within your
GUI, there are some circumstances where you don't want your process
running in other threads, so in such circumstances use
QDDisplayWaitCursor ( TRUE ) to bring the beach ball up quicker and
then pass it FALSE to stop the beach ball.

Basically if your applications event queue isn't serviced by your
application (usually managed by NSApp using the main thread) after a
short amount of time (2 seconds?) the OS will put up the spinning
beach ball. In general one should attempt to avoid having it displayed
(use secondary threads for longer processes). Also it is best to show
a progress bar or spinner on you GUI in situations like this then the
beach ball... most folks using Mac OS X consider the beach ball a sign
of a hung/broken application.
