hello SV,
I've had that happen to me. Usually if I take too long to post. I think it may either be hackers, overloaded servers, or just a timeout. Just try it again. As long as you are logged in, it should go through. Also, I've noticed some pages taking a long time to load. Almost stopping halfway through. Not just because of pictures. Close the page,reopen and it loads right up. I attribute this to the same possible causes. Jim.
