Reset my password or root's. This happens when, as me, I run "su" then 
root's password.

I don't want to change either of the passwords, so I'm thinking

$ passwd -d dan
$ passwd dan

Unless there's some other record somewhere I think that should "reset" 
each password.

If I start an xterm, after I've logged in and run "startx," I can't 'su' 
in the xterm right now. What you suggested is what I like to do.

That vim alias would be convenient help for me.

Thanks again, Bruce.
