Dan, there is an ongoing discussion on CNCdrive forum about this. I also thought it was fixed, but now after a few more minutes of thinking perhaps it is not possible for UCCNC software to take care of this for anything else than itself and for the macros since that is under the control of UCCNC. Everything else, like a plugin, is actually independent of it and must take care of the culture info on its own. So I think when Balázs answers my last post, his answer will be this. In other words, I think you need to add those two lines at the very beginning of the plugin.
