Cannot find Screen Mode in PS Elements 14

I let someone else use my program and have not been able to get my screen size back to normal when opening a new image to edit.  It opens full screen on the 2nd monitor, instead of within the program on the same screen.  I searched for help and was told to look for the Screen Modes under the View Menu, which it is not.  How would be the best way to get back to usuable normal.
