Me thinks the logging in automatically problem may have been overridden by browser "save password" features, I also think much of it is to do with differences between browsers, cookie settings will also have an effect.
From a security point of view it's never a good idea to tick the "log me in automatically" box
but I'm a geek so that's how my brain works
PS. It might also happen when I clear the temporary files at the forum's back end
