Well, truthfully, I sympathize. But as I see it, our job is to give our
users options, to empower them not hobble them. There may be a way to do
this - I wouldn't be surprised, anyway - but I've never tried.

Besides, the very first piece of virus code I ever examined was in some
flavor of VB - VBA/Word, I think it was - and one of the first things it did
was remove some user option from the menu so a naive user wouldn't easily (or
at least accidentally) find an option that would help him defend himself
against further infections. That was a long time ago, but I guess it marked
me. I'd have to really want it to go looking for the way to do it now.

Maybe someone else will tell you whether it's possible.
