We have a slideshow on the front page of the site, and it's working perfectly in every other browser except IE8. Even there it loads fine when first entering the front page, but after navigating to the other pages, on return to the front page only the running circle appear. If the page is refreshed, the slideshow appears again. The same happens it the language is switched while on the front page. Like said, no problems whatsoever on other browsers I've tested (Opera, FF and Safari, yet to test with Chrome).
Any ideas as to what might be the problem would be greatly appreciated!
