anythingSlider starts on the last slide in IE

I've added the CSS-Tricks anythingSlider to a page - it works correctly in Firefox and Chrome but in IE8, it starts on the last element instead of the first. This is a known bug apparently - Googling got me this...
---
When AnythingSlider is initialized on a hidden element, the last slide will show instead of the first. This is because a scrollLeft value cannot be applied to a hidden element. So either initialize it with visibility hidden, or if that isn't possible, then set the scrollLeft when it becomes visible:

    var s = $('#slider1').data('AnythingSlider');
    s.$window.scrollLeft( s.$window.width() + s.easingMargin ); // may not work if resizeContents is false (width will vary)

Can anyone explain how I implement this in my page, please? (not being a JavaScript/JQuery guru). I have a sample page here... http://www.cobwebbery.co.uk/anything/page.html which demonstrates the problem. I've obviously not done it correctly because I get an error '$window is null or not an object'

I've selected 250 points not because it looks like a huge problem but simply because I've got a client who needs this on Monday morning. BTW as you'll see from the site, the order of the slide is very important, so they must display in the correct order.

Many thanks
