The OS is XP Pro with OE6
If I go to toolsselect recipients all is well and what I consider to be my
current address book is accessed.
But, if I simply start typing the recipient's address, it tries to fill in
an address that looks as if it is from a different address book. One clue
is that my usual address book lists name in last name order and uses caps as
the initial letter. The "rogue" book starts filling in names based on first
name and they are often lower case.

In an effort to find the this address book, I have tried doing a search on a
name that was lower case, but none of the files located were address book
files.
