OK... When the window is maximized or restored, the target width/height is
provided in the newWidth/newHeight params, and only the newWidth param seems
to be something to "lock" onto. Secondly, maximizing on MacOS X leaves a 10
pixel margin on all sides and doesn't go out the full distance (i.e. on a
1280x1024 screen, the width of the window after resizing is 1260, not 1280).

So this code will detect Maximize/Restore, or will show the current stack
rect if you're not maximizing/restoring (works for Mac/Windows - haven't
tested on Linux):

on resizeStack newW,newH,oldW,oldH
  if the platform is "MacOS" then put 20 into tAdjust
  else put 0 into tAdjust
  if oldW = (item 3 of the windowBoundingRect)-tAdjust then
    put "Maximized"
  else
    if newW = (item 3 of the windowBoundingRect)-tAdjust then
      put "Restored"
    else
      put oldW,oldH,newW,newH
    end if
  end if
end resizeStack

Let me know if this works for you guys...
