Thanks for the clarification, Lax.

I always ran my G13 with a generic profile, independant of applications/games, so I'm safe on the automatic profile front. I will have to stay clear of the MR key, though, as it has the same function as on the G11 and G15. I hardly ever use M keys at all anyway, I have one profile only, and change actions in game with modifier-paged action bars.

Anyway, back to the point. I disabled all bindings on G-keys, left the thumb stick bound to it usual direction keys with Logitech Profiler running, and everything works fine.

Great feature !
