Can anyone explain to me why...

If I take a while to think about a post and take my time to answer it, I get logged out and when I log back in, I get this message... "Invalid Thread specified. If you followed a valid link, please notify the administrator"?

You get logged out automatically when there is no activity for a specific period of time. (I think it is fifteen minutes, but I'm not sure about that.) You can avoid this by clicking on the Remember Me button when you log in. Also, when you have to take time to think about a post before answering you should go ahead and click on the Reply button right away and then write something in the reply box and click on the Preview Post button frequently. This will register as activity and keep you from getting logged out.
