[Solved] PDF being attached after upgrade from 2.6.6 to 2.6.8

[mowlman]

After upgrading from 2.6.6 to 2.6.8 I now am getting redundant PDF invoices attached to the email invoice sent to customers.
Is there a switch to disable the attachment or do I have to hack / override?

thanks.

UPDATE:  In VM Config 0 checkout Tab,
Default Order Status to create an invoice     I selected only Refunded and no other.  Now I still get the confirmation emails, which for me, also serves as the order invoice.
This setting is strictly for the PDF invoice and is automatically attached in email to customer. 

So since I set to Refunded, if I refund an order, then a PDF attachment would go out to the customer.  Some people create a new order status of "No PDF" or "None" and then set the above field to that.

I think I will do a language override and change "Default Order Status to create an invoice "   to say "Default Order Status to Attach and send PDF invoice" just so when I or someone looks at this in the future, they will know this is dealing with the PDF invoice and not the normal order confirmation .
