Persistence of a window's title?

[Steve Ross]

Is a screen-window's title supposed to persist?

I have created two windows in one "screen" session.  I have titled them both by typing "CONTROL-a" followed by a colon followed by the word "title" followed by my title, one for each window.

I have the titles permanently displayed at the bottom of the window by two lines in my "~/.screenrc" file:

    hardstatus alwayslastline
    hardstatus string "%w"

I don't know if it makes any difference, but I also have

    altscreen on

The problem is that the screen-window titles do not persist.  After I enter a command like "ls", the title changes to something like

    username@machine:~/Man

where the directory name is the first first three characters of the name of the current directory in my home directory.

Is the lack of persistence working as designed, a bug, or am I missing something?

My version/release of "screen" on Fedora is 4.6.2-8.fc30.

Thanks for any help,
