3. You could provide an explicit menu command for the user to invoke to
reopen the window, as Mail and iTunes do. But that's just another way to
invoke the underlying functionality you're talking about in point #1.
Whether the application should quit automatically or not when the last
window closes is very app-specific and more than a little subjective.
It's a behavior that should generally be adopted by very single-purpose
tools that in a prior life might've been implemented as desk accessories
for example. Something where closing the window is a very clear signal
that the user is "done."

What object did you link it *to*? I've only done the briefest of
dabbling with AppleScript Studio, but for Cocoa that handler will only
be triggered if it's implemented by an object that's designated as the
delegate for the application. It wouldn't be something that, for
example, you associate with a window.
