WP 3.5 Probs

Hello, today I updated WP to 3.5 and now Fancybox doesnt work anymore with IE9. With Firefox everything is fine. The background darkens, but the pictures are not loaded. In the changelog of WP3.5 there is something mentioned with jquery. Maybe you can fix it? Thank you and merry xmas!
