Log Out not working?
 

Recently I find that after I've logged off, using "Log Out" and getting the usual message including the word "random", when I come back to mersenneforum.org I'm still logged-in!

I don't recall having made any recent cookie-affecting change to my browser or security software settings, but apparently my login cookie is no longer being deleted.

Is there a forum-related explanation for this recent inability to log out?
