Help with Apple Mail

[kingshrubb]

Something happened to my Apple Mail... whenever I used it in the past when I clicked on a new message a preview of it would appear in a tab in the bottom. Now it doesn't and I have to double click every message for it to pop up in another window. How can I fix this? Thanks!

There's a little bar at the bottom to drag up.
