[Butterfly Bill[_2_]]

I have been having this problem with my Word 2007 (12.0.a bunch more
numbers):

If I assign to a chapter name the style Heading 1,
and then in the page headers put in StyleRef fields for Heading 1,
and some of the names have three or more words,
and I format the whole name field in the header in something like
Bold,

sometimes not all of the words in the name in the header come out
formatted the same. If the name of one were "the Very First Chapter",
sometimes only "The Very" or The Very First" will come out in Bold.
The rest of the words are in whatever is the Normal font. This happens
with character styles, fonts, and sizes.

This happens when I open up a document that has been saved after
closing Word and reopening it. If I go into Edit Header and correct
them all, then save it, all the corrections are lost the next time I
open it.

This is frustrating because I want to use different fonts in the
headers.

Anybody else have this problem? Is there a way to fix it? It seems
like a glitch in the Word program.
