[wp-hackers] How to prevent "You do not have sufficient permissions to access this page."

[Mike Walsh]

One other ramification of the functionality being split across PHP files,
the Admin menu doesn't stay expanded because the "current" page isn't part
of the menu.  The more I think about, the more I think I should combine the
functionality but as this isn't my plugin, I am trying to limit how much of
it I change.
