Hey there,

I have exactly the same problem.

Since Cinema4D R21 I have this problem on two systems (work and home).
Both on 13″ Cintiq’s, the newest model and the older hybrid version, both 4k screens of different brands and both Windows 10 Pro.

It’s even worst in my situations. I have to toggle the cursor back to the main screen, but when I do that I am unable to click anything, the cursor is there, I can move it around, but it doesn’t seem active. The workaround, to get it to work again is Ctrl+Alt+Del, then start up ‘Task Manager’, and as soon as that window opens, it becomes active again, and I can click something..
But then again, as soon as I open a window in Cinema, I have to start all over again..

Have you found a fix for this?!
I am unfortunately still looking..

Cheers,
Chuck
