I presume these animated watch cursors are implemented by installing a
vertical retrace interrupt routine. If so, they aren't a very reliable
guide to whether the application as a whole is still operating. My guess
is that the watch cursor will keep turning as long as you can move the
mouse.
Do you really sit there looking at the animated watch cursor so you can
tell immediately if your application has crashed? If so, you need more
reliable software.
