Thanks for looking so quickly. I should of put a bit more context around it.
So in your screencast the final link you click next to the address is the one I am referring to. If you click on the reviews tab and the click the reviews link the page will navigate properly. If you then click on another tab then review link again nothing happens. I have recorded this for you.
