email address book
You used to list email addresses by alphabetical name and now you list them chronologically. That makes an address hard to find!

Alan, You can remedy this yourself. Open your address book and click on the column title that you want reordered. Each time you click on a title it will alternate the sort, either forward or backward alphabetically (as shown by the arrow following the title). Let me know if this helps you.
