Re: Handle Dock menu open/close events

I am not certain if this will actually work, but you could try doing
performSelector:...inModes: in the preprocess step, and passing the
NSDefaultRunLoopMode as the mode. Theoretically, while the menu is open,
you'll be stuck in event tracking mode, and the selector will not be
called. Once the menu closes, you'll go back to the default mode and
wham! Your selector will get called.

I don't know if it will work because this technique /didn't/ work for me
with drag-and-drop in an outline view, due to what seems to be a bug in
Apple's outline view code :(
