Thanks for the information.
Could you tell me from what plugin that custom menu is, so I may directly test URE with it?
As about “Block not selected” option, it works currently as straightforward as it named – blocked (as result user is redirected) all not selected URLs. So if some link is clicked from the allowed page, but that link was not selected at menu items list (it may even be not presented there) user will not get access to it.
