dired-hide-details-mode have no effect suddenly

[Tomas Nordin]

Hi List

Here is a problem I don't know how to reproduce. I have this in my
.emacs:

    (add-hook 'dired-mode-hook 'dired-hide-details-mode)

and details are hidden by default, the way I like it. Sometimes I need
to see some details and I use (default I think) the key ( to toggle
visibility of details.

However, suddenly after some long time of keeping emacs alive, details
are always shown and I cannot toggle it. I have been trying to detect at
what moment this happens but I fail to understand what the interference
is. At this point all I can think of is restarting emacs. Did somebody
notice a similar problem?

Best regards
