I have been using Mac Mail withiout difficulty for years. My acreen has always consisted of three Mail sections: 1) the sidebar with my mailboxes listed; 2)a list of all the messages in a given mailbox (with thumbnail descriptions and blue dots indicating unread messages); and 3) a section showing the full message or messages for a given item in the mailbox list. This week, for no reason I can discern, the third section has disappeared -- and I can't for the life of me discover how to get it back. Can someone help?
