In Mail, I lost the split screen, while in Classic layout
Until recently, on my iMac Mail App, I was able to view the body of a selected email in a screen directly below the listing of all mail in a mailbox. This feature has disappeared. How do I cause Mail to provide the listing of emails in the top screen divided by a bar and the contents of a selected email in the screen below the bar ?
PS: I see the little dot in the narrow bar, on the bottom of my screen, but moving it or double-clicking it does not raise up the desired screen.
