Thank you again.

I'm running a cygwin system, with cygwin tcsh shell and cygwin vi.

LAPTOP-2LPUB1MQ:~ 54> which vi
vi:      aliased to vim
LAPTOP-2LPUB1MQ:~ 55> which vim
/usr/bin/vim

I don't have any local vim customization files, my user minttyrc and
tcshrc files are attached.

Thanks again,
Eric Adams.
