Not working for me - menu items not restricted and overall menu settings have no effect

Hi,

I don't know if I'm doing something silly, but I've followed the README and it doesn't seem to work at all. I'm not clear what permissions users should have for "administer menus". Should they all have that permission, or none and your module sorts it out? I tried both ways and neither behaved as expected.

First, I tried to hide the admin_menu module's menu from normal users by setting the permissions on the whole menu. I got an error saying the menu name was required and could not save.

So I tried the same thing on a custom menu. This time no errors, but the menu was still visible to excluded roles on the node edit form. I removed the "administer menus" permission from the excluded roles to see if that would cause a subset to be shown, but it just removed the interface completely. =(

So I tried the same with menu items further down the tree of the Navigation menu. Settings were saved without issue, but again, menu items still showed to excluded roles.

I'm not sure if this module is totally broken or I'm doing something stupid. Any suggestions?
