ephox causing network prompt when loading

Hi

When users load ephox for the first time a network prompt appears. I spoke with technical support and they say older versions of ephox did used to obtain licence information but this has now been removed.

Is this due to the client machine loading in the ephox config file? Is it trying to authenticate with the proxy server?

Has anyone else experience the same behaviour? and ultimately how did you fix it?

Cheers
James
