What I meant was that Vim is now at version 7.3.138. You apparently
are using 7.3.0. This is probably OK--I do not see any bug fixes
related to screen drawing or special keys--but you are missing out on
a lot of bug fixes and minor feature additions.

Vim ships with a ton of runtime files which control all sorts of
functionality. In addition, your system may have a "system vimrc"
which runs before your own config files. Are you telling me that none
of Vim's runtime files are installed? If so I would almost expect you
to encounter problems. Additionally you tell us that all the config
files are the same. Is what you really mean, "I have no config files"?
I.e. do you have no ~/.vimrc, no ~/.vim, AND no environment variables
set which affect Vim startup?

You mention a few specific key mapping problems (thanks, that should
help somebody) but your original email mentions that "the screen
display changes". What sort of changes do you see?

I do not know enough about how terminals work or how Vim interacts
with them to be of much help here. Someone else should be able to pick
up from here if you keep the discussion on-list.
One thought I have, is that even if all your config files are the
same, Vim is very configurable at compile time. Were both versions of
Vim compiled with the same options? Compare the output of the :version
command from each Vim version. If one is HUGE and one is TINY (for
example), or if one is compiled with specific features the other is
lacking, this could be another source of problems.
