I finally got to confirm the settings. By default, my CAD-leaning Lenovo P70 running Windows 7 Pro didn't recognize Cura as a 3D app. Similar situation with an older Dell running a similar hardware configuration. The top bar menu simply does not show up, and mouse click positions are offset. I know this has been going on since V2.3 because that is when I gave up on this last time. My Win10 laptop just isn't equipped for Cura.
Today I added Cura as a 3D app in the NVidia desktop. Left all the setting at default and restarted Cura. Now Cura is running on the NVidia card and the menu finally shows up.
Thanks guys:
