I just reinstalled Outlook 2000 on my computer.  Now my Contact List (the
list I click on to add a name in the "to" field, appears sorted only by first
name, not last name.  I cannot access a last name.  Before reinstalling
Outlook, the list always appeared alpahbetical by last name.  

All previously entered names in the Address Book are still correct and the
"file as" names as correctly shown as last name comma first name.  However,
when I went to enter a new name today, e.g., John Doe, the "file as" name
appeared as John, Doe rather than Doe, John.  All names in the Contact List
now show up as John, Doe -- not as Doe, John.

How do I fix the problem?
