The File Menu in ArcMap 10.2.2 is suddenly missing a whole bunch of commands, including Export Map. Anyone knows why, and how I can restore the File Menu?
Many issues with ArcMap, particularly UI-related issues can be fixed by renaming your Normal.mxt file. It can be found in the %APPDATA%\Esri\Desktop10.2\ArcMap\Templates folder.
(Renaming is preferable to deleting the file, so you can roll back the changes if you need.)
