Using Office 2003, XP Pro, SP2

After many, many months of working fine, my Contacts list is no longer
available when I click the "TO:" button when creating a new message.  It's
defaulting to a different folder name that doesn't exist.  My "real" contacts
list is available in the drop-down.

I went to add/remove address books and deleted the errant folder, so now the
only address list showing is my contacts list.  However, that old folder
still shows up.  Haven't done anything different with the computer lately.  
Got me scratching my head.

Ask your questions and I'll clarify.
