Hi Greg,

Just a quick general response.  (I'll send you a detailed e-mail
description of my technique, but will only give a brief idea of it
here.)

I found out shortly after Win 95 came out, it was the most corrupting
thing to my DOS installation, so I reformatted and created two
completely independent and fully isolated operating systems.  That way
I can keep all my DOS programs in a pure DOS environment, DOS 6.22,
and any programs that need to run under Win95 are installed and run in
that environment.  It works fine for me.
