That fixed it, looks great now!  It was a flickering NSPopUpButton 
that was causing me grief.

I assume they are as I've just created a bunch of custom views in IB 
and set their frames there.  Would there be a better way?  If they 
can't be resized by the user, is it worth calculating their values on 
startup and just caching them, even though I calculate the new frame 
before the animation?

Thanks very much Scott,
