I usually run as root when updating systems (toor actually)...

But symptoms are same for root and user level in vi, FreeBSD-[5.4,6.1,6.2,6.3].

NO nfs mounts, aliases, or any other funny stuff I can think of.

Virgin vi setup from FreeBSD install.

"inside_vi :!" --> (ANY ! command, not just macro)
The ! command is not supported when the secure edit option is set.

"inside_vi :set all" --> (same as 4 other FreeBSD machines...)
