Subject: Ediff frame loses focus under certain circumstance
Date: Sun, 3 Jun 2012 19:23:17 -0400

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


This is with Windows Emacs 24.1 pretest build 1
Start emacs -Q
Open two files (small and similar will do)
open Tools menu->Compare(Ediff)->Two Buffers...
Hit enter twice to get the two suggested buffers
Hit ? to expand the Ediff control panel commands
Hit n to get to next (first) diff
Hit b to copy diff from B to A
Hit n - and Ediff frame loses focus, goes to B instead


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/Program Files/Emacs/etc/DEBUG for instructions.

IIUC you can change this by removing the line

	   (not ediff-use-long-help-message)

from the function `ediff-recenter' but for some reason the current
behavior seems the expected one because `ediff-setup-control-frame'
looks at the value of `ediff-use-long-help-message' when deciding
whether to auto raise the control frame or not.

I suppose this is not from the 24.1 pretest build.

You are right! I found the bug when running 24.1 pretest, but when I
ran with -Q my PATH got me the old emacs (which I kept in case of
catastrophe with 24). I have now reproduced the same bug using the
same keystrokes in a clean 24.1 pretest, here is its debug report:

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
c:/Program Files/emacs-24/etc/DEBUG.
