I'm having trouble linking to a previous thread. When I click on a link in a current thread that refers to a previous thread or image, I get the following message: "You must be logged in to do that." Below that, it asks me to log in with my name and password or join as a new member. When I insert my known user name and known password, it displays the same message and will not take me to the link I asked for. What gives? I have no trouble opening images or threads that are current. I also have no trouble posting new threads or looking at new postings.
