Mouse invisible over Artboard

I teach Illustrator to High Schoolers. For tutorials - I mirror my screen to a Clevertouch screen so students can see what I'm doing on the larger screen. When I do that, my laptop screen shows my mouse 100% of the time. But on the mirrored screen, the mouse appears in the Application bar, options panel, toolbar, and properties panel. But it disapears over the artboard! This makes my follow along tutorials a bit tricky for students to see what I'm doing! This is only happening in Illustrator. No issues in Photoshop. My IT guy and I have tried googling and finding a setting but having no luck figuring out how to correct this.
