Messages suddenly started to show Message ID, User Agent, X-account-Key and other source information etc and when I try and reply to a message it shows all the source information before the message. How do I get hide all this information?

Thanks a lot. I was ready to switch to Postbox I was so frustrated. That little switch made a huge difference. Thanks for your help. I'm sticking with Thunderbird for now.
