Check out Bar - bug / permission

[widgetuk]

There's an option in Boss Cart JV to enable the Checkout Bar upon user checkout process.

In my opinion these are great to guide the customer through the process of checking out so that they might see where they are in the whole process.

BUT, after the first stage of checkout (ie. after the Shipping Address), the Bar no longer actually displays, and only the text links are displayed.

Does anyone recognise this problem, and know what the solution is perhaps?

Thanks, Jon
