Controller Axis calibration in FSX

As probably many of you will know, in FS2002/2004 you could easily correct a non-perfectly calibrated, or slightly "jittering", axis- without-logical-center (like a throttle or toebrake axis) by adding a small "dead-zone", by moving the "NullZone" slider a bit above the MIN value. To avoid problems like "thrust reverse doesn't work" or "hanging toebrakes".Unfortunately, this doesn't work anymore in FSX.If you now increase the NullZone slider in Options-Controls, FSX still creates a "dead-zone" for the axis, but not at the low-end of the axis, but at it's "center".Even worse, the Sensitivity slider for these type of axis not only influences the "range" of the axis, but also shifts the "zero" point upwards.Unless I am missing the obvious, this makes the calibration functions in FSX for this type of axis completely and utterly useless IMO.So be warned.Regards, Rob BarendregtPS. Before someone reacts with suggestions on how to do this in another way:Yes, I know all about "stick_sensititivity_mode" in the .cfg file, the way to "mis-calibrate" the axis in the Windows Controller menu to introduce this dead-zone, using calibration programs supplied with your stick/yoke/pedals, or even using the registered version of FSUIPC for calibration.But it really beats me why MS decided to cripple this very usefull function that worked fine in previous FS versions. Unless of course MS didn't intend to change it, but then I'm enclined to call this a new bug :-(
