Mystery vim7 versus vim6.4 - same term, different results

Actually I've got version 7.3.43 with cream on windows. But I do not want the
pain of trying to compile vim on a machine where I do not have root privileges
and I do not know where the sysad people put needed files. The sunfreeware
binaries will be fine.

Specifically, the site has the runtime files for 6.3 installed in a wierd
place -but they are there (/util6/SUNWspro/contrib/vim/share/vim/vim63/).
I did install those for 7.3 in my friend's home directory under ~/vimfiles.
But VIMRUNTIME and the other vim environment variables are undefined. There is
only the traditional .exrc in $HOME, which vim finds by default.

I do not see what `problems' I would encounter by not scripts and files. They
are extra, and not necessary for the executable to function.

For special tests, I do point VIMRUNTIME to the right places. It does not
correct the terminal problem.

Again - no vim related envirenment variables, one .exrc file in the home
directory which all versions of vim read.

With 6.4 keys and screen seem fairly normal with term=vt102. But with the same
term and 7.3 -- all kinds of things go crazy. Motion keys insert text, and
make the cursor jump to odd places, the j key writes the file to disk -- too
many things to mention here.

This is the most likely source of the problem. Of course 7.3 has gobbs of
extra features including client-server, python, ruby etc. Most particularly,
it is compiled with GTK2 GUI, while 6.4 is compiled without the gui. Im used
to launching gvim when I have a gui, so I do not know what it means for the
console vim to be compiled with a gui. But it may be doing graphics related
things that confuse a text based console interface.
