I having a problem resolving closed orders, I need to able to change status of orders that are being delivered from 'pending' to 'delivered' - but for some strange reason when I use the drop-down option in Shipments and select 'delivered' then I hit submit - The changes are not being saved nor are the comments I input the comment text field box, the screen just does quick flash then still shows as if it's waiting on me to hit submit to save the changes. I don't have this issue changing order status from 'processing' to 'pending' only when I need to 'deliver' the order then it doesn't work. Am I missing something in the order fulfillment process which isn't allow me to close them? OR is the a magento bug error that I should ask my developer to look at an fix? I attached a short screen cast video so everyone can see what I'm doing and I would great appreciate any insight and advise on what to do before these orders pile up.
