duplicate orders paypal pro

[belgariad]

Version is 1.3.9h
PHP Version: 5.2.11
Database: MySQL 5.1.36
Apache/2.2.11 (Win32)

I'm having the same problem, but it only happens once in a while. I just had a customer place an order and all of a sudden I receive a duplicate order and each order would have a different PayPal transaction ID. It was process by PayPal Pro because I see the client used VISA to pay for the item.

So far, from what I can see, it happens at least once a week or once every 2 weeks.
