mouse wheel doesn't work

[Scott Otterson]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing 
list.

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

Wheh I roll my mousewheel, I get the error message

     <triple-wheel-up> is undefined

(or down).  In emacs 21.3.1, using the same mouse, OS and .emacs, the
mousewheel works.
