One of the problems with Internet Explorer 7 is that it sometimes stops Javascript
and Flash from running.
These features are needed to run the activities on our web site.

If you click on a resource and an empty window opens and no activity runs you need to either use another browser such as Firefox or follow these steps. (30 seconds to change)

All our resources should now open correctly.

We have had some additional help from Chris at a school in Aberdeen.
To solve the problem where some PC's can open the resources and others not.
This may be that the Flash browser plug in is installed but not running.
To quote Chris "basically I had to give a user account local administrative permissions and install it with that account rather than as the domain administrator."

For those visual learners here are a series of screenshots.
