I wasn't able to get the jcenter utility to work in Windows XP Home, even with compatability mode. Probably wouldn't work in Windows NT or Windows 2000 virtual machine / command line either. The properties button seemed to produce a suitable substitute for most functions. Both POVs showed on the same indicator.On my system the rudder I use on the gameport with the yoke was only showing the upper half of the travel in the calibration dialog (accessed through the control panel) but showed full travel in the simulator, which I started after finishing the calibration.
