bug#9628: 24.0.90; resizing window vertically does weird things on OS X Lion

[Jason Lewis]

--text follows this line--
Resizing the window vertically on OS X Lion behaves very strangely.
as you drag up or down, the window jumps all over the place. then when
you let go of the mouse button, the window dissapears. CMD+Tab to
another app and back and the window re-appears but is usually very small
and at the top of the screen.

Steps to reproduce. Start emacs on OS X Lion. with the mouse, grab the 
bottom
edge of the window and drag up and down.
