TOPIC: Multiple Event Cart fails on 'no cost' events

When an event with a zero cost is selected and the data entered, the system goes directly to the 'thank-you for registering for...' page without asking if I'd like to "register for another event". If there happen to be events in the cart that require payment, they disappear.

Also, it seems that the contents of the cart may disappear if the user does something other than click 'register for another event'. For example... if they use the menu to get to the list of events. This isn't a critical problem, but most users will expect the cart to stay alive while the look at other stuff on the site.

Thanks for the great work on 2.7... I need the 'cart' functionality to make DT Register useful for my client.
