This site works with a piece of simple harmless java script which creates the menu bar and pop-ups within the site. These enable you to navigate easily and offer you relative information without the need for enormous amounts of text to be displayed on a single page. Unfortunately if you are running WindowsXP SP2 or Vista the new security center automatically blocks any active content within a page whether harmless or malicious.

You can remedy this by doing the following;

If you cannot see the Stage Truck menu bar in the top left hand corner of the screen , please select 'Tools' then 'Internet Options' and in the Security menu check the box next to 'Allow active content to run in files on my computer'.

Or simply when Internet Explorer gives you a 'pop-ups blocked for security reasons' bar then please click on the bar and select 'Always allow pop-ups from this site'.
