My guess is an issue with term settings between Putty, screen and your
shell.  It has been ages since I've ran screen so my memory is a little
fuzzy, but I believe screen would set your TERM to "screen".  You might
check to see if you have term definition for screen:

|find /usr/share/terminfo -type f|

Not sure if it is an option, but you might switch to tmux from screen. 
So many improvements over screen it is hard to start.
