DPP4- button to return to thumbnails missing

[Sborg]

See attached.  When I started a session to work with some thumbnails in DPP4, there was a button in the upper left of the Edit Image screen that would return me to the thumbnail screen.  Don't know what I did, but that button disappeared.  Does anyone know how I can get that button back?  Thanks.
