In playing with this, I see that if I add something to a cart, then go to the Paypal payment page, then check the Stuck Paypal list, it shows the transaction.

Am I right then that what likely happened is that the customer went to the Paypal page but never completed the order, thus leaving this transaction on paypal hanging? Is the way I can tell it is an actual order is if I see the transaction listed in the Paypal account listing itself, then I push the order to the store database? In other words, did I add an order that was actually never completed in the paypal payment page?
