Confused over checkout workflow

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.5

Hi, I am confused about the checkout workflow and how to make it work the way I think it should. The checkout works fine up to the point where the user has registered/logged in. Their shipping amount is predetermined by weight and is added to the order. The current only payment method is Paypal which is pre-selected.

At that point, the user clicks "Finish" to complete the checkout and the system redirects to Paypal to take the payment. But at the same point - prior to any payment being made and returning to the site, an email to both the purchaser and the site owner is sent out. For both, the email says a new order has been created.

Can the emails about this not be sent out after the payment has been made and therefore the items have actually been purchased? It is confusing because sending the email before the payment has been made suggests that's it.

How can I change the workflow until after the payment has been made. Please can you explain.

Thanks in advance.

This stops the emails, which is good, but is there a way of returning to the cart, because the customer may of bought a lot of items and then just before logging into paypal, they decide to cancel from paypal and add another item to their basket, they get peeved off if they have to start all over again.
