I'm not sure I understand: Do you mean here "OS X doesn't allow windows
above the top of the screen"?

I've never been able to "drag" a window above the top of the screen
because on all machines I know of the title bar is the handle for
dragging.

Does this "OS X allows an application to place a window above the top of
the screen" hold _only_ when the menu bar is hidden or does it hold
regardless of that? What's such a restriction good for anyway?

Because Emacs "normally" advices OS X to constrain the frame to the
screen. Correct?

Why? Do you never use the fullscreen feature?

It will happen when it's too large and you specify negative values for
its position.

OK.

OK. The "when" might be an answer to one of my questions above.

Agreed.

Fine.
Thanks for your efforts, martin
