Address Book auto update (sync?)
In Address Book I have a friend named in Jessica. When she sends me an email it reads in mail as coming from "Jessica -" (I guess this is how it's configured with her mail provider). So when I reply to that email Address Book updates "Jessica"'s entry to read "Jessica -" (first & last name), when I don't want a last name at all.
Also, when I compose a blank email, I start typing Jessica and the To: field displays as "jessica - <address@place.com>" until I change fields and then it displays as "Jessica <address@place.com>". However, once the email is sent, Address Book is edited so her entry is "Jessica -".
I've tried looking in the preferences of both programs, but don't see where this action is controlled. Any help is appreciated.
