(2003) Different first page when using letter wizard

I have used the letter wizard to set up my letter leaving a 5cm space for my
letterhead. However, for some reason, Word is assuming I wish to print every
page of my letter on headed paper, and has left a 5cm gap at the top of
every page (there are two pages). I have attempted to use the header and
footer settings and set 'different first page' but that hasn't worked -
there is *STILL* a 5cm gap at the top of the second page.

How do I set it (and I'm sure there must be a setting I'm overlooking) so
that the gap is only at the top of the first page - different odd and even
hasn't worked either.

Word 2003 SP1 on Windows XP Pro SP2.

Or am I blonde?
