I've still got the problem - flickr are supposed to be responding to me - have set up a case number but nothing back yet (don't suppose they work at the weekend!!) There is a flickr forum somewhere and there is loads on there about people all over the world having this problem. I have the flickr sight bookmarked and must have specified to keep me logged in and that lets me in straight away with no need for password but if I try on a different computer be it mac or pc then it loops at password. Also doesn't matter what browser you use, still a problem.
