Word - save font-size as percent?

[Jud McCranie]

I asked the following three days ago in ms.public.word.web.authoring,
and I haven't gotten a reply, so I'll post it here.

I'm making some simple web pages in Word for XP. It is working well,
except that in IE 6, changing the font size doesn't change the size of
the font. I found out that if I manually replace font-size in points
with percentages, it worked correctly in IE. Is there a way in Word
that I can tell it to embed percentages for font-size so I won't have
to make the changes manually?
