Below the folder bar, the window is divided into two frames. The frame to the top is the current folder frame and at the bottom of the window holds the current message . Each of these frames is resizable. The horizontal divider between the message frame and the frames above can, similarly, be moved up and down. You can change the order in which messages are displayed by clicking on Sender , Subject or Date to sort by one of these characteristics.
Date is the default.
Note that you may have to widen the current folder frame to see the date. You can flag individual messages by clicking the dot under the red flag in the status bar. New Msg - Create a new mail message. Reply - Allows you to reply to the sender. Forward - Allows you to forward the selected message.
