Modify order without notify customer

[sandomatyas]

When I open an order in admin I can modify the order status, append comment and there is a checkbox if I want to notify the customer.
But when I try to modify a single order line or some price/tax related data of the order and click on the save link, VirtueMart sends email to the customer and the vendor every time, I wasn't able to disable it.
Of course it's only true when the current order status is available in the " Default Order Status to send email to shopper " config field, but in this case it is.

Did I miss a setting maybe?
