I disagree.
If you supply all three choices, you are misleading your users that there is
a third option avaliable.
For example, you are posting a table to a database, and you detect what
*may* be a typo with your error checking code, so you ask your user whether
or not they want the 'problem' to be fixed automatically. The yes and no
choices are easy enough, but if you have a cancel button, the user should be
able to expect that by pressing it, they can cancel the whole operation
altogether...

Steve,
I think all those boxes should have yes/no/cancel buttons even if
cancel does the same as no. :-)
