Subject: View-quit in *Help* restores wrong window when
display-buffer-reuse-frames is t
I received the bug report below from an Aquamacs user.
A little investigation traced this to the setting of `display-buffer-
reuse-frames', which, when t, causes "View-quit" to do the wrong
thing when restoring the previous window configuration.
In this case, the second window in the frame gets deleted, but the
first window switches to a different buffer.
The following should reproduce it in a 22 branch CVS Emacs (with
unrelated patches - I tried Aquamacs with -Q) and also in a 23 one (I
tried Adrian Robert's Cocoa port):
(progn
(setq display-buffer-reuse-frames t)
(describe-mode)
(other-window 1)
(View-quit)
)
