How do I stop gmc from starting when logging in as root

[Mike Kistler <mkistler io com>]

Hello!

I would like to stop gmc (the gnome file manager) from starting up
whenever
I log in as root.  I don't use gmc very often, and it displays this
annoying error
message about running it as root.  I know this question has been asked
many
times before, but the only answer I've seen is to "save the current
session" without
gmc running.  On my system (RH 6.2), this doesn't stop gmc from starting
... it
just makes sure to kill it once it has forced me to click "okay" on its
error message.

Many thanks in advance for any help or advice on this.

Regards,
