Mouse middle button no longer a push button in calendar diary

Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,

In GNU Emacs 21.4.2 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2006-02-03 on pc2
configured using `configure  --prefix=/opt/emacs'
Important settings:
  value of $LC_ALL: en_US
  value of $LC_COLLATE: C
  value of $LC_CTYPE: en_US.ISO-8859-1

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. Under Emacs-21.4.2, while the calendar is displayed in, say, the bottom
   part of the screen and a diary is displayed in the other part, pressing
   the middle button of the mouse when the cursor is over a diary entry
   does not change the background color of the entry to green as it should,
   the pop-up instruction "mouse-2, RET: push this button" does not show up,
   and pressing the middle button returns the error message: Buffer is read
   only: #<buffer *Fancy Diary Entries*>.  

2. The function works properly under Emacs-21.3.50 but fails
   under Emacs-21.4.2.

3. Both versions of Emacs share the same "site-lisp" directory.

4. Here is what the "describe-bindings" has to say over the "diary" part of
   the screen for both versions of emacs.  I show just the beginning of the
   listing in both cases.

This is not a bug. Emacs-21.4 is the latest _stable_ version of Emacs,
Emacs-21.3.50 is an (old) version of the _development_ branch. So in
some confusing sense, 21.3.50 is "newer" than 21.4.

(Explanation: ages past, 21.4 was expected to be the new development
release. 21.3.50 was a pre-version of this. But then 21.4 was released
from the stable branch. Current development version is 22.0.50.)

The feature you describe only exists in the development branch, so is
not in 21.4.
