screen vs sh

["ratio" <ratio%insight.rr.com@localhost>]

Hi! I just installed screen (version 4.00.03) from pkgsrc-2007Q4. Now,
instead of cursor movement & history, the arrow keys give me escape
sequences. I'd imagine it's just a matter of termcap/terminfo tweaks, but I
know next to nothing about that. Does anyone know the magic incantations to
restore the cursor keys? I'm using PuTTY release 0.60 with all the defaults
and sh from a bog-standard install of 4.0 if that makes a difference.
