Can't 'forget' old addresses
If you have the option "Add new contacts to "Emailed Contacts" selected in Preferences > Address Book, email addresses you send a mail to will automatically be saved in the Address Book called Emailed Contacts.
If you then remove this marker, the addresses already saved will still be kept in this Address Book until you delete them yourself, and therefore they won't disappear from the list either, even though you choose 'Forget'.
To remove the address from the list, you have to delete the address in your Address book first.
