no matter where i use:
$menu->entryconfigure(#,"disabled);
i get:
Can't locate object method "entryconfigure" via package
"Tk::Menu::Cascade"
unless i use it on a non-existent $menu, in which case i get:
Can't call method "entryconfigure" on an undefined value
Also, if i add a -command in a cascade(), i get no warnings or
complaints but perl ignores the command and simply opens the menu. I
would like to call a command when a submenu is opened to determine
which entries are available; surely this is possible?
