I have used httrack to capture a site for offline viewing, however, the
interactive activity will not show if I am offline.

If however I go online, the interactive activity will then show; I assume this
is because the activity is accessing the original website.

I have tried to save the website twice and in both cases the problem is
present.

How do I save the entire contents of the site?
The site in question is:
<http://www.shodor.org/interactivate/activities/ShapeSorter/>

Thanks....
