Richmond, I did your thing of creating a button with a script in it: on mouseUp assert 1 is 2 end mouseUp
on assertError answer "It isn't, you know!" end assertError It worked entirely as expected - the object containing the command (the button, in this case) received the assertError message as per the description. However I am still extremely unsure where I would use it in place of try-catch, but FWIW it does work.
