ibuffer kills split window

[Peter Lee]

I prefer to have ibuffer use another window.  If I have a single
buffer visible and call C-x C-b (which is bound to 'ibuffer), a new
buffer is displayed and when I press q it goes away.  This is fine.

However if I'm working on 2 buffers (split), and I do C-x C-b,
ibuffer takes over one of the buffers (whichever one did not have
focus at time of call).  And when I press q, it buries the buffer and
I lose the window... I have to resplit.

I much prefer the way bs-show did it by popping up a completely new
buffer and when 'q' is pressed things are restored exactly as they
were (even if I have 3 or 4 split windows).

I rely on ibuffer filtering though, so I'm hoping there's a way to get
the old bs-show behavior.  If this is broken then is there a
workaround?  If it's by design, then is it possible to get the old
bs-show behavior through hooking and if so any ideas how I might do
that?

My current ibuffer settings:

(setq ibuffer-expert t
      ibuffer-fontification-alist '((10 buffer-read-only 
font-lock-constant-face)
                                    (15 (string-match "^*" (buffer-name)) 
font-lock-keyword-face)
                                    (20 (and (string-match "^ " (buffer-name))
                                             (null buffer-file-name)) italic)
                                    (25 (memq major-mode 
ibuffer-help-buffer-modes)
                                        font-lock-comment-face)
                                    (30 (eq major-mode (quote dired-mode)) 
font-lock-function-name-face))
      ibuffer-use-other-window t
      ibuffer-default-shrink-to-minimum-size t

      ibuffer-saved-filter-groups
      '(("pal"
         ("dired" (saved . "dired"))
         ("source" (saved . "source"))
         ("html" (saved . "html"))
         ("gnus" (saved . "gnus"))
         ("erc" (saved . "erc"))
         ("hidden" (saved . "hidden"))))

      ibuffer-saved-filters
      '(("html" ((or (filename . ".*\\.asp.*") (filename . ".*\\.htm.*") 
(filename . ".*\\.js"))))
        ("erc" ((mode . erc-mode)))
        ("dired" ((used-mode . dired-mode)))
        ("gnus" ((or (mode . message-mode) (mode . mail-mode) (mode . 
gnus-group-mode)
                     (mode . gnus-summary-mode) (mode . gnus-article-mode))))
        ("source" ((or (mode . c++-mode) (mode . emacs-lisp-mode) (mode . 
cperl-mode) (mode . c-mode)
                       (mode . java-mode) (mode . idl-mode) (mode . lisp-mode) 
(mode . makefile-mode)
                       (mode . visual-basic-mode) (mode . csharp-mode) 
(filename . ".*\\.cls")
                       (filename . ".*\\.vb") (filename . ".*\\.bat"))))
        ("hidden" ((name . "\\*.*\\*")))))


Thanks for the help.
