I really do not understand the concept of tab here. If by tab you mean a new window, then, as I said, I cannot control that. If by tab, such as "secondary" tab, you are making reference to the bottom frame, then all appears ok for me. Because, when clicking View from the top frame, the messages will appear in the message frame. So, all appears ok to me up to that point. Can you elaborate more on the topic?
