Disclaimer: I'm not an investor in PuTTY, just a satisfied customer :-).
I've been using PuTTY for years with vi, vim, emacs, screen (and heck even
joe, nethack, and bsdgames sometimes) primarily to Linux/Solaris/FreeBSD
systems. I've never encountered the problems you describe. I'm not saying
they don't exist, just that it's likely something other than PuTTY causing
the problem.
I've seen the behaviour you describe when using a vt100 terminal emulator to
display e.g. Sun console escape sequences. What type of system were you
accessing with PuTTY? My guess is that somehow your terminal type was
incorrect in your PuTTY sessions, but not in your ssh session. Or maybe it
was an ancient version of PuTTY?
