Help: Gumball disappears!

Hello! New Rhino user here going through the training documentation (Level 1 Training Guide) to learn the software and I ran into the section “Editing with gumball”, and my gumball has disappeared.

It was there a week or two ago in the earlier pages of the training manual and now it won’t turn on. I right clicked the ‘gumball’ button on the bottom bar and turned it off and on and still no result.

I also have a hybrid graphics situation (Intel Graphics 630 and Nvidia Quattro P2000) and when I disabled the Intelgraphics most of the apps went fuzzy; I did check to ensure that the Nvidia Control Panel is using the Quattro P2000 to run Rhino.

thanks!

Dave

EDIT TO ADD: Apparently there has to be geometry on the screen for the gumball to appear. facepalm

Hopefully this helps some other newcomer like myself.
