I've had several years of the 1.0 version successfully processing many transactions. Thank you for such an excellent port! With the most recent upgrade, I am experiencing an issue that cptok said may happen.

I've successfully upgraded my cart to 1.3.9h. After confirming that, I upgraded QBMS from 1.0 to 1.9. Ran a legitimate production transaction and it processed without a hitch creating one order. Since that test, I have had three duplicate orders/transactions. One duplicated the order and the QBMS transaction, which I had to manually refund. The other two only had duplicate orders (different order IDs) yet the customer's cards weren't charged twice.

I also noticed on the legitimate test transaction I made, there was the line in the order's status history:
[CC PMT] [Visa] AUTH: 000000 TransID: MA0000000000
I zero'ed out the AUTH and TransID for web safety. Above the Products section within the order screen, it gives me information about the credit card type, name, last four digits and expiration. Since that transaction, not a single credit card order has had any of that information. Why would it just stop posting those status updates and the credit card info? Nothing changed from the test order to normal production mode.

All the files have been checked with WinMerge and are identical. I'm having to "cancel" the duped orders and that doesn't actually cancel the order, putting the product back in stock and removing the sale from the sales reports. Anyone have any advice?

Thank you for your thoughts!
