One of my solutions is missing the fmp “save or send a copy” button at the top left or could it be covered over?
The standard FileMaker File Menu is attached.
If your menu doesn't have a lot of these items in it, you probably have custom menus in place. FileMaker Pro Advanced is required to manage these menus (File > Manage > custom menus).
If your menu item is greyed out, it may not be available. For instance, "save a copy as.." menu item is not available on files hosted by filemaker server.
Are you perhaps referring to the Status toolbar?

Is you file located on a server, if so that's the reason.
