As the subject say, it seems like the CheckoutDoneOrderIsComplete event is not fired when using the "epay - payment window" checkouthandler.
Looking at the log we do get the callback from epay, containing the transactionnumber, so that is fine, and the order do get set to completet in DW.
I just missing the notification, so i can do a bit of extra work :)
Solution is runing on DW version 8.6.1.16
