Apple Mail, Version 12.4 (3445.104.11) - "Preview" window has disappeared?
In the "Classic" view of Mail, the emails are listed one per line across the top of the screen, and when you click on one, that email text shows up in the window on the bottom half of the screen. You can drag the border between the list and the "Preview" window up and down to change their percentage coverage of the whole screen.
Well, my Preview window has disappeared, I only have the list at the top, and NO viewing window below! How do I get my window back? I've tried toggling the "Classic" selection on and off, and I've restarted Mail, nothing! Can't find any direction in any "Help" sections ...
Any help would be most appreciated!
