I am setting a custom view containing a label and spin style progress

style)
to spin in Menu..
Haven't tried this, but a lot of animation is done using timers.
Timers have to be scheduled using in a particular run loop mode. I
guess while a menu is open, the run loop mode is the tracking run loop
mode.
Maybe you could schedule your own timer for the tracking run loop
mode that calls animate: ?
Alternately, I think NSProgressIndicator can be set to use a thread
for its animation. That should fire even in tracking run loop mode.
But be careful, threaded animation (like pulsing default buttons or
spinners) inside a custom view can cause your custom view to be
redrawn from a non-main thread. You'll have to make sure that your
custom view is thread-safe, or you'll get very subtle threading bugs.
