the easiest way to lock gnome panels?

[Alejandro Castán Salinas <alexcastan gmail com>]

Hello,

my name is Alex from Barcelona, and I am not an advanced user of Linux.

I write you for one question. Sorry if it is too basic. I didn't found
the information on Internet.

Some volunteers installed four recycled computers with Gnu/Linux+Gnome
in a association what help refugees. Most of this people (refugees)
come from rural zones where they never had a computer. Sometimes they
start experimenting alone with the mouse and the desktop, and hide the
Gnome panels, so they don't know how to make it appear a new panel and
build the applets and desktop, and the desktop becomes blank and
useless.

Do you know which is the easiest way to protect gnome panels? Sabayon?
Gconf? or change the attributes of some file from the command line?

Thanks a lot,


  Alex
