Title: Two Problems - Address Book and Mail View

Hi,
    My Entourage application went south. I imported what I had saved previously. I updated to the 11.2.4, which I hadn’t done previously.
    Question 1: How do I get the address book to show up when I am composing?
    Question 2: How do I get my Mail View “Received Today” to once again show up taking up the entire window?
Thanks so much,
Reney
