Question about Outlook Express

I have set up two separate WLM email accounts on my new computer, changing over from XP and OE. Easy Transfer brought over the old emails. However, it also transferred our two individual address lists as one cluster from OE and WLM is using it as the master contact list. I can't figure out how to create/access separate contact lists for the two individual accounts. My wife's massive list comes up when all I want is my 26 name contact list. I can see my list as a Category(?) in Contacts, but can't access it when I want to create or forward an email. How do I access my small contacts list or set up two separate contact lists for our two separate accounts so I can avoid her huge list? This is for picking and choosing specific addressees for any given email, NOT for a Group mailing.

All my experience is with OE and I really like the completely separate mail accounts, settings, contacts lists of OE. Am finding that WLM and W Essentials, sign ins, and other unnecessary actions very annoying to say the least just to send out a simple email.
