Thanks, that lead to investigate the .emacs file and I traced the
problem to a snippet I got from the Emacs Wiki concerning the speedbar,
to prevent it popping up in another window:

https://www.emacswiki.org/emacs/SrSpeedbar

(defadvice delete-other-windows (after
my-sr-speedbar-delete-other-window-advice activate) "Check whether we
are in speedbar, if it is, jump to next window." (let ()
	(when (and (sr-speedbar-window-exist-p sr-speedbar-window)
               (eq sr-speedbar-window (selected-window)))
      (other-window 1)
	)))
(ad-enable-advice 'delete-other-windows 'after
'my-sr-speedbar-delete-other-window-advice) (ad-activate
'delete-other-windows)

Although I do not know much at all with lisp and lisp used in emacs, it
looks like a specific target is used, sr-speedbar although there is
a more generic function used: delete-other-window, about which context
execution is not clear (for me).
