I’m having problems, too, with logging out. When I click Log Out, it does nothing. But if I switch to my Profile, it gives me the Login Form on my Profile page. But if I go back to the Home page, it remembers my previous login. This happened with the original theme, and is still happening with a new theme. This happens whether I have a session logged in with my WordPress installation or not–it doesn’t seem to be related. This is a serious problem. I can’t launch a bbPress-based site with login/logout not working.
