In Lectora 2009, it does not recognize When Done with Flash. Is it fixed by now?
Maybe you can have an array in Flash that starts with 0 and turn to 1 whenever you click the button. e.g. contentArray = [0,0,0,0] In the same script, check the array if it becomes [1,1,1,1], show the Lectora button? I can't get the show something from Flash to work though.
