OK, one comment off the top.
I see no Core Animation in this example. This is strictly
NSViewAnimation or Animatable proxies.
Which part doesn't work?
is it when you have layer backing turned on? or off?
what does your drawing method look like?

Fellow list members..
I have been round and round with my choppy resize animation.
Basically I have a custom view in IB that contains 3 subviews. I am
trying the iTunes "show/hide" artwork effect. Basically I have a
NSTableView that is wrapped in a custom nsview that displays
financial transactions and the view underneath displays a detailed
view of the selected transaction. To trigger the resize, the user
just double-clicks the transaction and I resize both custom nsviews.
shrinking the deatil view down and expanding the transaction view
so that the transaction nstableview takes up any remaining space. I
am guessing that I am redrawing excessively which might be causing
the "choppiness". I am open to any and all suggestions. I have
pasted the relevant code below.
Thanks,
