      Description

        To reproduce, run the attached test program on a Windows 10 system with the Windows 10 1709 (the Fall Creators update) with screen scale set to 125% or greater. It will fail to move the mouse to the correct location.

        Before you run it, move your mouse to a corner of the screen.

        Note that any number of Robot-based tests will also fail in the same way.

        This seems to be a bug introduced by Microsoft in Windows 10 in the mouse_move function.

        I note that FX robot also fails similarly.
