OK, I can now see what your Mail window looks like.
Not sure why there are two images with the exact same name. I didn't think the OS would allow that! But it's not a problem here, anyway.
However, those images are of the Mail Prefs. I'm looking for a screen shot (or list of items) in the Mail View Menu. My Mail app has the following menu choices: Mail, File, Edit, View, Mailbox, Message, Format, Window, Help. In Reply #6 above, I posted a screen shot of my Mail->View menu. I'm looking to see what choices you have in that specific menu.
