Hi @Proks
The function preview wouldn't work on Windows Azure Websites, as we use PhantomJs to generate images, and it relies on GDI+ api, which is disabled on virtual mahines on Windows Azure Websites.

That said, you shouldn't see a loading screen, as far as I remember, there should be no preview generated, but rather boxes with function names should be shown instead. Do you have any errors in javascript, or in C1 server log?
