More information. In the command windows I enter:

set bell to "c:\vfplogs\error.wav"
?? chr(7)

This plays my .wav file.

I enter the command:

on key label f9 do testbell

procedure testbell
set bell to "c:\vfplogs\error.wav"
?? sys(7)
=messagebox('TestBell')

I get the default sound, ding, and I get the messagebox.

I repeat the ?? chr(7) in the command window and get my .wav file

I repeat the f9 and get the default ding and messagebox.

I shut foxpro down and restarted with the same results.

hmmmmm!!
