This seems to be a new problem, which suggests a Microsoft Update to Windows 10 may be responsible.
The calibration screen within FSX is treating my Quadrant as if it is a joystick. i.e. X and Y are getting treated as Axis within the square box, whilst Z is normal band from 0-255. I've uninstalled and reinstalled all the drivers, cleaned out the registry using the script provided by Saitek/Logitech, and nothing I do seems to change it.
Setup is:i7 4790k processor, Geforce 980GTX graphics, 16GB RAM, ASUS ROG , Windows 10 Version 1803 64 Bit
Am I alone in seeing this problem?
P.S.
Also possible to crash FSX whilst trying to calibrate.
