Before you get too far into this I thought you should know that "Master
Document" is a term of art in Word referring to a "feature" that not only
doesn't work but also destroys documents. The consensus (with the limited
exception of Steve Hudson) among those offering advice on these newsgroups
is that using the Master Document feature is a sure way to destroy your
document. It can destroy parts of your document that you are not even
working on! I think John McGhie said it succinctly when he said that there
are two kinds of Master Documents: Those that are corrupt and those that
will be corrupt soon. See <URL:
http://www.addbalance.com/word/masterdocuments.htm> for information on the
Master Document feature and workarounds. (This page also has a link to Steve
Hudson's chapter on how he gets Master Documents to work.) See <URL:

information on what goes wrong, and <URL:

how to salvage what you can.
