An e-commerce system shouldn't send a second transaction when hitting the back button. It should void the session & the shopping cart.Not a shot at PMDG, just saying

Glad its all sorted out amicably. For the purposes of the OP (first poster) just like you over reacted (and apologised readily) so did some of the forum. But its such a good company, products and forum some of us get over protective at times. You`re quite safe here in this forum and with PMDG, I can assure you. PMDG are one of the better companies in flight simulation as well as the leading models. I hope from here on in you enjoy the forum and use it any time you need advice, help or to enjoy a little banter about aircraft and simulation.Steve
