Plugin doesn't work properly in Chrome

Hi,

I’ve observed that the plugin doesn’t work properly in Chrome and IE. The scrollbar displays but it will only scroll to a certain point, cutting off any content is still in the div. After refreshing the page, the problem disappears. Asking users to refresh every page is not really a solution, though 🙂 Check out: http://www.heinvergeer.nl/wie-is-hein/ijzeren-hein/. Any help or suggestions would be appreciated.
