When using the ELP Remote Programmer on your PC, the mouse speed
is too slow or too East.
The ELP Remote Programmer mouse speed and the Windows Control Panel
mouse speed may be interfering with one another. First try adjusting the mouse
speed in the ELP Remote Programmer’s Special menu. If this does not solve the
problem, adjust the mouse speed in your computer’s Control Panel.
