I dunno what kind of broadband you're on Ken but if I were you I'd ask for my money back..
Here's the same thing for me in the first image, and of course that only happens on the initial load, afterwards the browser will cache the js as you can see in the second image..

You have to take into account though that this is a pretty damn complicated web app with quite a few external libraries that we need to embed directly in our package due to security concerns. Ideally we'd pull Highcharts etc from elsewhere but we prefer not to take that risk, so it's packaged with the app.
