I use screen with a configuration that allows me to see the name of the tabs on the bottom of the screen.  I've used this configuration for many years, on many different hosts.I installed screen on a CentOS 7 machine.  I use this .screenrc on another CentoOS machine, and it works as expected.  The .screenrc is being used on the new CentOS machine, I can tell by the way the window looks (colors, bar at the bottom).  But one thing is not working as expected.  I can change the window title by pressing control-A, A, and typing in the title.  However, on the new CentOS machine, the old (default, e.g. bash) title will come back after I've exited a program, vim for instance.What might cause this?
Screen window title reverts after running a command on my new machine
gnu screen;window title
