I would recommend checking your $PROMPT_COMMAND - some shell configurations
reset the Xterm title, and screen can pick that up as a window title or
pass it through depending on your environment.

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
