When I first tried to post to this board, my posts never got through. It was some time before I found that if I was returned to the main list, the post had gone off into the blue. Nowadays, when I make a post, I find that the first time I post it, it often returns me to the main list of messages. If I go back and do it again, I am returned to the actual post I am contributing to and my message is there. I don't know if the problem is in my machine or your software, but there is certainly a problem.
PS It happened again with this post.
