If someone has their security setting put to High is it possible to
either change their setting to Medium programmatically, or get a
message box to pop up and tell them that they need to change their
setting to Medium ?

(I realise that none of the above is propbably possible as the security
setting will be well protected.....but thought I'd ask anyhow, as a lot
of people know nothing about Excel and blame my code when a program
doesn't work - when it is simply that they have their settings too
high)

Any help appreciated
