How do I keep same date messages together?

[Anne London]

For a time all current messages were at bottom of scroll. Then messages
arrived scattered everywhere regardless of date. Then (for no apparent
reason) current messages were at top. Now they're scattered again. I have a
Mac. What can I do?

Hi Anne!

Are you possibly clicking a column header, such as "Subject" or "Date"
or something else that is sorting messages according to that header?
