iTunes help, anyone?

The pane in the iTunes window that shows all my playlists has vanished and I can't figure out how to get it back. Anybody have a clue?

Upgrading worked, thank God. The iTunes upgrade check thing didn't believe that 4.8 was out, but going to the iTunes website provided the ability to download 4.8, thankfully.
