We have a couple of users that have been receiving this fairly regularly when running credit cards using the html5 interface. Wondering if anyone else has been having this issue. When one of our user's customers places an order for over $100,000.00 and comes in to pay with a credit card and this happens, it is very disconcerting to their customer and time consuming to get into cenpos and find the transaction to see if it went through or if they have to retry the card. We have switched back to the flash interface but that is going away very soon.
