This was originally developed/tested under XP.

At the time, some who were running Vista reported not hearing the confirmation beeps.  I recently upgraded to Win 7, and saw the same issue.  There is a Window's Sound not set in Win 7 that was set by default in XP.  (I forgot which one.)

You can tweak Vista/Win 7/Win 8 through the control panel.  You'll find a screenshot enclosed here of how to do this in Win 7.
