Context-free error messages during debugging

[Mark Schonewille]

Hi Graham,

You could adjust the message box to throw errors instead of  
displaying them in its lower field, but it is probably easier to  
create your own message box and save that as a plugin. Just make a  
palette window with a field and the following script:

on enterInField
   do me
end enterInField

This kind of errors (Chunk: can't find card) occurs after referring  
to a property of a nonexisting card, such as

put the bla of cd x
put the name of btn x of cd y

Sorry, there are too many possibilities to give an exact cause of the  
error, but I hope this helps anyway.

Best,

Mark
