I need to add new events to a previously defined event registration refnum, a task that's starting to seem impossible . Well, in fact I've managed to add two event refnums (from their typedesc, plus some scripting, etc). It works, but... the new event registration refnum, though it has the correct structure, it doesn't have specific controls registered on it (of course), so the events never trigger. I'm running out of ideas, so if anybody has one to offer... Saludos, Aitor
