This probably looks a bit confusing because I cut the wrong piece of 
text.  I was playing around with the
declaration to make sure that I hadn't shifted the argument labels 
myself, and the WINDOW
argument is incorrectly typed as :DOUBLE-FLOAT. Here's a correct 
tracing of the call

CALLING -[HemlockWindowController windowWillResize:toSize:]
   SELF = [:ID] #<A Mac Pointer #xBFFFE550>
   _CMD = [:<SEL>] #<HEMLOCK-WINDOW-CONTROLLER <HemlockWindowController: 
0x8530f2e0> (#x8530F2E0)>
   WINDOW = [:ID] #<A Mac Pointer #x9089F61C>
   SIZE = [:<NSS>size width=-8.316439E-36 height=600.0]
-[HemlockWindowController windowWillResize:toSize:] returned [:#<A Mac 
Pointer #xBFFFE4B4>] <NSS>IZE

With the correct argument declarations, the size argument is now 
shifted back 4 bytes (because WINDOW is really 4 bytes, not 8)
and is now wrong. SELF, _CMD and WINDOW are, of course, sitll bogus as 
well.

Ideas?
