3.1.7 Touchscreen calibration failure

1 monitor connected, non-touchscreen Acer connected to Monitor #1

I was trying to calibrate the touchscreens on the main console with a single monitor connected. I could calibrate the touchscreen first on the right hand side, and then, the calibration would move to the external monitor (a non-touchscreen); and therefore wouldn't allow me to calibrate the second internal monitor. I would do some gestures on the right touchscreen to see if it would move to the left internal touchscreen, but to no avail. Seems like a bug to me.

I could replicate this with restarts. The only way of correcting this before the show was to reset the console without any external monitors connected. This allowed me to use both touchscreens and calibrate each one; however I had to give up the external for fear it would destroy the calibrations again.
