Hi Daniel, Thank you for all your help on this - I managed to get access to the request logs as you suggested, and it turns out there is a corporate firewall/proxy messing things up.
Basically the request for "loader.js" is being intercepted and redirected to a network security holding message, which sometimes redirects to a network security login page. Unsurprisingly this causes some problems for the Google charts on the app. I suppose it's possible that this is related to the loader change, if something which was introduced at your end which the corporate firewall doesn't like - but in any case it doesn't appear to be eitehr my code or the google loader which is the root cause!
