Thanks for the suggestions, EinsteinEP. The one about the Enable Clutch option on the MFD tab was spot on, so I now have an useful extra button.
The pinky button still is a mystery to me, as I can say for sure it's not stuck and that latched option isn't on. Just as an example of strangeness, if the profiler software was not loaded, the game detected the pinky as joybutton6, I could add it in the modifiers list but it would work a click-to-activate, click-to-deactivate modifier (not as hold=active, not hold = not active). If the profiler software was running in the tray, but no profile was actively loaded, the game no longer detected it

... go figure.
However, in the end I managed to make it work , using the profiler, I'll have to live with that, so now I have double the commands, and that's great.
If you have the time, maybe you could post your setup/bindings for the stick?
