trouble creating a "real" SuperAdmin


I'm a relative newbie, so sorry in advance...

I've created a new "SuperAdmin" account via the WP admin console.
This user can login ok, but is
lacking access to things
like NETWORK ADMIN (we're using
multisite), USERS and several other
items that appear on the left side
of the WP console. I verified the
account has SuperAdmin access.

I'm guessing there's another step(s)
i need to do. Can you point me in
the right direction please?

Thanks for your help
