[newbie] Netscape address book

[Digital Wokan]

I realize this isn't a Mandrake only question, but under Windows in
Netscape, I can type a partial name and Netscape completes it from my
address book.  Having added several names with nicknames to
Linux/Netscape's address book, I have yet to see it successfully
recognize any of those entries as I compose a message.  (Ex:  I put
newbie in as a nick to Mandrake Newbies, but NC kept insisting that
there was no match and wanted to put [EMAIL PROTECTED])
Anyone got a suggestion?
