No, I am checking if PrgHandleEvent returns false, I call PrgUserCancel and
abort.
But I click on cancel many times and PrgHandleEvent never returns false, and
thus PrgUserCancel never get called.
Any idea why?
Can it be that the 1/2 second is too long (if the operation is quick) for
the system to get the event?

Are you saying that PrgHandleEvent is never returning false? Or are you
expecting the system to call PrgUserCancel for you? It's your responsibility
to call PrgUserCancel when PrgHandleEvent returns false, and to actually
abort the operation when PrgUserCancel returns true.
