When saving after adding items to display case and pressing "Confirm"...the text below "Display Case" briefly reads "You did not select any items" and then disappears.
Then the Display Case is saved and does not give the option to arrange the order of all items, as I believe it used to do. So I have to go back into "Manage items" to re-arrange my items.
I'm using windows7 and the latest Firefox.
edit: tested and same results using Chrome
