         Could you review the updated fix:

          The MSDN doc says that the SPIF_SENDCHANGE broadcasts a 
message after updating the user profile. Probably we do not want to 
notify all that we disable and then enable the beeper for the RICHEDIT 

         It allso says that this parameter can be zero if you do not 
want to update the user profile or broadcast a message.

        So the fix sets the fWinIni parameter to 0 in the 
SystemParametersInfo method.
