When you are in the open order screen and you click an order which you would like to delete (for example if it is marked as 'dispatched by other courier'), it opens up in its own window (painfully), then you click the delete button however the order stays open and you have to manually close it. Very confusing at first because you are unsure if it has been deleted, now its just annoying.

It would be a much better flow and much less confusing if it takes you back to the open order screen
