Try attaching your animation to either "frameOrigin" or "frameSize" 
instead.

Those are the primitive properties in NSView's model of things, with 
"frame" being more of a convenience for getting or setting both at 
once.  View property animation treats frameOrigin and frameSize as the 
primitives as well, to facilitate their being animated potentially 
independently of one another.
