Difference between products and 'normal' pages sidebar

Hi,

I am very happy with what I have been able to create to date, but I have one issue remaining. On the site http://www.italiaansesmaak.nl the button of the cart widget align nicely on the product pages, but overlap on other pages (e.g. http://www.italiaansesmaak.nl/?page_id=382).

I have been looking everywhere on how to resolve this, but have been unable to find it. I would appreciate any help…

Regards,
