[JW Lua] Crashes on MAC,2

[Jan Angermüller]

Do they get a crash or an error message?
Did you have a chance to check yourself with the Finale document where 
the crash occured?

I have just quickly browsed through your script to see if I find any 
classes/methods that I remember to be able to cause crashes.
I would recommend to put a nil check after 
smartshape=mark:CreateSmartShape()  (i.e. add "if smartshape then" ...)
This can return nil in some cases and would AFAIK produce an error 
message on Windows (but probably not a crash - I am not sure).

I noticed that "staves" in the function apply are not used.

In one of the first messages that I exchanged with Jari he recommended 
to more or less check everything for nil.
And a few years later I can say ... yes, that was a very good 
recommendation. Especially if you deal with slightly corrupted or older 
Finale documents.

I like your preview button :-)
