The Automic Script editor can´t open Includes from Client 0.
Due to security rescrictions which prevent users to interfere with objects in client 0.
There is no possibility to view content from Includes client 0 in your current client.
As a workaround you can establish a connection from every Dialog Client to Client 0 and view the Inculde there. We would recommend to create a user with read only rights on these objects to avoid unwanted changes in your system client from usere.
