I discovered by accident that the Lenovo Windows tablet (X220T) now supports using the pen to scroll and pan. I assigned the function to the pen button.
And it works great in Logos4. I can also adjust the scroll speed.
Then I tried it in Bible Places. Works! Zooms in/out, with the normal pen moving the map.
So if you have a windows tablet, you might keep your eye on pen driver updates for your PC. Lenovo also fixed the pad scrolling in Logos4 too earlier.
