Prestashop 1.6 Guest checkout on separate page question?

[ukbaz]

Hi I'm running last version of Prestashop v1.6.1.24 and have 5 step checkout with guest checkout enabled.  This currently drops down the checkout area when button clicked rather than going to a separate page as the log-in and non-guest checkout options do.

Has anyone any idea how I can make the Guest checkout button redirect the guest checkout so it follows the same logic as in existing customer login and new customer login options?

Thanks
