Once I have an email address in the address book I can't seem to change it. I have written some names incorrectly, but when I correct them, they flip back to the incorrect version. Also every email a friend has ever used is in my machine somehow, and once they change email addresses the old ones also show up and I can't remember which is the new address without rechecking my address book each time. How can I delete old addresses that show up when I write an email and wrong addresses in the address book. I have tried deleting and rewriting but it still keeps returning to the old wrong item. Thanks
