Up to two days ago, when composing an email, I would usually type in the first letter or two of the addressee's name in the "To" space. If that name was included in Address Book, it would come up right away. That has suddenly changed. Now that works only to bring up GROUP addresses. But for individual names, I now have to first select the "To" button and then go through a Select procedure in another dialogue box. How can I restore the previous functionality?
