bug#37840: Missing in the Emacs manuals:

[Konrad Podczeck]

Thanks for your response. I have another question, on the following 
customization:


(setq display-buffer-base-action
       (quote (
  (display-buffer-reuse-window display-buffer-pop-up-frame)
  (reusable-frames . t)
 )))

(setq display-buffer-alist
       (quote (
      ("\\*[^s][^s]" (display-buffer-reuse-window display-buffer-pop-up-frame)
       (pop-up-frame-parameters
        (width . 92)
        (height . 48)
        (left . 1150)
        (unsplittable)
        (tool-bar-lines . 0)
        (left-fringe . 0)
        (right-fringe . 0)
        (line-spacing . 0)
        (font . "Monaco-12")
        (top . 180)
      ))
)))

Suppose I have buffer A open in frame A. Issuing occur->some word, the occur 
buffer pops up in its own frame, say frame B, as intended with the above 
customization. Moreover, frame B has input focus. Returning to frame A, without 
closing frame B, and issuing another time occur-> some word, frame B now shows 
the new occur buffer, as intended, but this time frame B lacks input focus. 
What goes wrong the second time?

Let me mention that if, in window.el, I add 

(x-focus-frame (window-frame window))

at the very end of the defun "display-buffer-reuse-window", the problem goes 
away, i.e., in the above example, frame B gets input focus after every 
invocation of occur in frame A. How can I get this with a suitable 
customization on the "display-buffer-alist" level?

Thanks

Konrad
