After selecting the check boxes for printing sales orders the check boxes then need to be unchecked automatically after printing as it is easy to hit the delete button and erase the checked boxes. I did this today and had to re-enter the said sales orders a second time, this was caused by my having to erase a duplicated order and I accidentally unchecked the said order and pressed deleted which actually deleted all the other sales orders and not the one I selected to deleted. My fault but it's easily done.
