In that case, I don't know of any way to respond programmatically. It might
be possible by using some of the Windows API functions such as
GetWindowHandle and SendMessage, but that's not my area. Karl Peterson
(
http://vb.mvps.org/) might have something that will work.
Besides simply getting something to act on the message box's buttons, you
also have the problem of knowing when your code should run. I don't know how
you can do that, either -- it depends on when and why Word is showing the
message box.
