Sorry but for me left button, right button, it doesn’t make any difference. So I am not living the nightmare that some people used to only the left button live and it sounds like it is a big one ; worse I can’t understand it.
But I don’t want you to make me feel it ;). Just to tell me if the option among the Preference to allow selection with the left button works if you’re using it, if that solves the problem or not and, if it’s not the case, why does it fail ?
I ask this as an author of tutorial. That would help me greatly.
