Just started noticing this with my most recent install v2.2.2 - but it may have been happening before.
When I create a new CP Menu item it works fine while I am logged in for the session used to create the item. However, as soon as I log out, and then log back in, clicking the link in my menu requires a re-login.
I think this is because the Menu item is created containing the session variable in the query string. So clicking the menu link is probably creating a conflict once that session is terminated.
Anyone else experiencing this?
