How do I reverse Zoom in Mail?
How do I revert to the normal size Mail frame after using Zoom in the Window dropdown item? Using the small arrows at the border shrinks the Window but deletes lateral portions of the message list screen. Also, the same Zoomed effect remains when I then use Safari--when I shrink the panel, lateral portions of the Zoomed item are cut leaving the large central portion intact in the "Zoomed" article.
