Clarification & verification:
You are saying that:
-- The logo etc. are set up in the "header". Word's
literal Header, or one you are just calling a Header
because it's at the head of the document but still in
the body portion?

I'm calling it the Header because it is in Word's literal Header as
you refer to it.
The one that can only be changed if you select header/footer view.


-- She's typing away in the body of the document,
making corrections/additions/deletions. She's not
working in or on the Header.

From your description, the header is simply a part of
the body of the document, followed by a Section Break.
Why?


I must not have said it clearly enough then, because that's not
not what I THINK I said. When I say "She's working on the
document and all of a sudden the header is gone." I meand she
is working in the document outside the header.

Perhaps the confusion is because I said there is a section break
at the very beginning of the document. I believe this is the correct
way to describe it because it occures right after the header. As I
recall,
it is necessary in order to prevent the header from appearing on
subsequent pages. That is, the first page header is applied only to
the
section before this break, and an empty header is defined for
subsequent pages.

It would not be possible to inadvertantly impact the
Header if it actually existed in the Header area of the
document. Therfore, you seem to not be using Word's
Header & Footer abilties but instead have your header
in the body area.


Oh, but that were true! I'm not trying to be funny, but I am
telling yoy what happens, as strange as it sounds.

The "flip" answer is, well put the "header" information
up into the Header where it's protected.

It is.

But reason tells me there might be more to the story?
Every page has room for a separate space to hold a
Header and a Footer. You access it by View, Header and
Footer.

Understood. While far from an expert, I have been using Word for
as long as it has been around. I have created documents hundreds
of pages long. And I have used headers/footers. This is a strange
problem I have not been able to solve, so am posting here.

More to the story? Well, it's a two-column page layout, but the header
extends the full page width.

Are you using that method? If not, why not? It sounds
like a good "fix". With a good descrip, it might be
possible to find a better way if none of this helps
any.

Let me ask you this. Suppose you set up a document so that there is
Header A on the first page, and Header B on subsequent pages. Since
headers/footers "go with sections," in a manner of speaking, there
must be a section break somewhere between the first page and the
second,
else Header A would appear on the second page too. Now, suppose
all of this is working splindedly and then you select that section
break and hit
the delete key. What happens? Clearly, there is now only one section
so there
can be only one header, but which will it be? While writing this note
I
tried an experiment in my document. I put a line in the header for the
second section
saying "Section 2 header." Guess what? When I deleted the section
break
"Section 2 header" shows up as the header on the first and second
pages!
It turns out it is Header B that survives!

So, I understand what is happening a little better but the problem
remains. When
the section break is deleted the fist page header disappears because
it is
getting replaced by the header specified for the second and following
pages.
And in spite of contrary assertions by someone else who responded, it
cannot be Undone. the Undo is graryed out on the Edit menu.
It seems that deletion of section breaks cannot be undon under certain
circumstances.

Many thanks, Pop. I'll poke around at it a bit more,
but if what I'm saying is still leaving you puzzled, let me
know.
