Sorry that it has taken me so long to respond to your helpful comments.  I
have been working on it, and cearing out a virus...

I would really rather not have sound on that machine because of what it is
used for and where it is.

Sorry - I am finding this sentence confusing too now :-(  I set the system
up on Linux and enjoy using it but I feel that the musicians on our network
would get on better if they used LilyPond instead of passing the scripts to
me.  Unfortunately they are not willing to learn Linux.

I tried this but it looks as if cmdproxy.exe cannot run python.  I get the
message:

Yes...I have tried setting shell-file-name as a buffer-local-variable in
lilypond-mode-hook, but of course the buffer is *2ps*, not the .ly buffer.

Thanks.  I'm happy to keep trying.  I'll have a go at using your wrapper
suggestion next.
