Launch script with "Startup script" folder

Hello,

I have a script that process, save and close some documents.

I'm having some problems when I launch it using the "startup script" folder: when the script tries to close documents using the standard function myDocument.close(SaveOptions.NO), the documents aren't closed.

But, if I launch the same script with ExtendScript Toolkit, documents are closed correctly.

Any thoughts?

Thank you
