Hi,
I just learned about Zoomit!
I downloaded the latest version and tried to draw on the screen.
I have setup with 3 screens in total: the laptop screen + External Dell (set as main display) + External monitor.
I can draw fine in the external Dell set as main display, but if I press CTRL+2 in the laptop screen or the other external monitor, the mouse disappears and cannot be seeing again until I press Esc.
I'm using:
OS Name
Microsoft Windows 10 Enterprise
Version
10.0.16299 Build 16299
