There's an oddity about OS X that may be at the root of this:  the 
screen update mechanism with OS X's Quartz is very different from 
earlier models, and often needs to be explicitely notified to update or 
it will wait until its own update interval has occurred.

To nudge OS X to update is simple enough -- just add this to animation 
loops:

    wait 0 with messages

Again, I'm not sure if this is related to the Anim Mgr issue 
specificallty, but I've seen many cases where updates are being drawn by 
the Rev engine but not yet visible on screen (such as status info in 
fields to indicate loop progress), and this simple one-liner seems to do 
the trick and will hopefully be useful to others.
