Did you add your own javascript to the cart, either in the template or through the backoffice settings? If so that might be interfering so try removing it and see if it works then.
Are you using a custom template? If so have you run the html of the page through an html validator to make sure you have the page layout correct, i.e. no nesting issues, comments not properly closed etc.
