Ediff normally initializes its control frame to a location just outside
the viewable area of the monitor, then it brings the frame back into the
viewable area shortly afterwards. With Emacs on OS X, though, it seems
that a frame that left the viewable area cannot return.
The following code slowly moves a frame across the width of the monitor
until it's a little past the viewable edge, then brings it back.
(let ((display-width (display-pixel-width))
(dx 200)
(frame-x 1))
(setq frame-test (make-frame
`((top . 1) (left . ,frame-x))))
(sleep-for 0.5)
;; 1. Move it until it's off-screen.
(while (< frame-x display-width)
(setq frame-x (+ frame-x dx))
(modify-frame-parameters frame-test
`((left . ,frame-x)))
(sleep-for 0.5))
(sleep-for 1)
;; 2. Bring it back.
(while (> frame-x dx)
(setq frame-x (- frame-x dx))
(modify-frame-parameters frame-test
`((left . ,frame-x)))
(sleep-for 0.5))
(sleep-for 1)
(delete-frame frame-test))
On GNU/Linux, the frame comes back as expected. But on OS X 10.6 the
frame does not return to the viewable area (step 2). Maybe there is a
bug in the frame handling code for the NS port.
