I've recently had to switch my email client from Thunderbird to Evolution. I'm using 2.2.1 at home, and 2.4.0 at work. But I have a problem with 2.4.0 - there seems to be no message preview pane, such as is shown in



In 2.4.0, I can't get the lower pane with the message preview; if I want to see a message, I have to open it in a new window. I have no problems with 2.2.1.

Any ideas on how I can get 2.4.0 to work the way I want?

Thanks,
-A.
