Depends. There are some things you can only do using CGxxx calls, but
the NSxxx calls are much more convenient to use. Also, at least

Tried the above, but the GC version goes back to ballooning memory usage and
eventual crash.

Sorry - I forgot to mention that I am indeed wrapping my code in its own
autorelease pool. This should ensure that the only retain count remaining is
from intentional retains by other objects that need to reference my datasets.

I found the issue, it lies in with using SteerMouse (current version) Ver 4.0.3
(Jan 7, 2011). Somehow this mouse configuration app causes the mouse over &
mouse out to stop functioning globally in Mac OS X 10.6.6 (current version)
when switching a user, or when calling the Login Window.
