Headers in Editor

[David J. Ring, Jr.]

I have the strangest problem.

When I reply to a message in a new  installation of mutt,  what will 
eventually become the addresses, and subject, and In-Reply-To threading 
informaton becomes the top lines of the editor!

If I write over them, or delete them, I have no addresses when sending
the message.

How do I fix this?

I've reinstalled mutt, I've copied over my configuration files from one 
computer to this one.

The only thing I can think of is that I edited a few files with pluma
instead of nano.

Also on the main screen of the message it says:

Security: None (OppEnc mode) while all my other mutt programs say something 
pgp/mime.

I am also running mutt inside Xorg MATE Desktop.

Any suggestions?

Thanks,

David
