If you have dual monitors, and you are not mapping the tablet to the recording window, some anomalies can occur if your operating system has the desktop extended across both monitors.

So, if you map to the desktop, you will need to adjust your operating system to NOT extend the desktop across both displays. If you do not make this adjustment, the reported horizontal position of the pen will not be as you expect.

The reason is that, although you can map the cursor movement to a single display, the resolution (reported X-coord.) is still mapped to the combined displays. So, if your primary monitor represents 60% of the combined horizontal resolution of both monitors, the right-most position of the tablet will be 60% of the max-X coordinate of the tablet's ability. NOTE: This is only if you map your tablet to a single display.
