Thanks for answering - No, the same problem exists in the event browser. FINISHED is checked as global and greyed, so it can't be changed. So is COLLISION ENTER, I've just noticed. I just need to know if this might cause problems and, if so, what might be done. Edit: I also noticed that all the system 2D events - TRIGGER ENTER 2D etc. - are also marked global, but these are not greyed. So now I'm wondering whether or not I should uncheck them.
