I am trying to detect whether any window moves on the screen. As far as I
can tell CGScreenRegisterMoveCallback should let me do this. But in the
little test code below, which registers callbacks then waits 20 seconds, I
never see the message "Updated" or "Refreshed". The code builds and runs
without warnings.


Any ideas?


You need to create and run a run loop.
