Thanks for the reply.
All the JavaScript files are included as part of the package.
The only thing I can think of is we load a JSON data file from our EBS upon load, or when an update notification is received via PubSub. Obviously this is necessary to show the correct information related to the broadcaster so I would not expect this to be the issue.
The only other fail is with the load of jQuery. Currently we load jQuery from one of the files uploaded as part of the package. If we include the script tag as recommended by the tutorials, the script is blocked by the browser, and the extension doesn’t work at all.
