Notation Editor is not staying static when selecting a track

I have a a full 50 line score in a Notation Editor window. Every time I select a track in the Key editor window (a 2nd window) the score editor collapses to the one track I have selected in the Key editor. This is unacceptable ! I need the score in the Notation Editor window to remain static. I don t want to have to be constantly be re-initializing the layout of the full score when I make a change to one track. I have looked through all the editor preferences and can not get any of them to stop this behavior. I even went and copied my old Cubase 8.0 preferences into my new Cubase 8.5 environment with no luck. If this is some sort of enhancement does anyone know how to turn it off?
