Annoying JL Won't Let Me Log In/On

I try, and sometimes it claims I'm in, but then when I try to comment on a friend's post, I get an error message about not being able to comment anonymously. Or I go to look at my friend's posts and I'm told I need to log-on (which I've just done, but apparently not). Most annoying. Not even sure it'll let me post this mini-rant...we shall see.
