Set View/Headers to Normal. Press Alt if the Menu Bar with View is hidden.

Hi, Many thanks for your reply. I was intrigued that clicking * now shows a list of options which no longer includes “Hide Message Headers” which I had ticked when it showed on the previous list of options. Toggling between normal and all in the view headers options does not seem to restore the “Hide Message Headers” option in * Thanks again, Wayne
