screen uses information from the original $TERM to help with its
optimization.  Sometimes that doesn't work well - in the cases that I use
and have noticed it, I've added screen.something, e.g., screen.linux, etc.

then that might be the problem - I'd try first setting up to use the
"putty" entry that I mentioned.  (Setting $TERM inside screen tends to
confuse it, of course).

but then I'd have to set it up and look around for the bug - takes a lot
longer than just having you try the one thing I can think of.  (If it's
not resolved, I add it to my to-do list, which keeps growing ;-)
