Quite possibly -- is there something it *should* be doing?  (I don't mean to suggest 
I particularly think there's not, honest question.)  I had figured it was a minor 
oversight and the warning was sort of a "spurious" one, though I'm admittedly well 
out of my depth here, so perhaps I shouldn't be doing such things (though I suppose 
it's one way to learn).
