I've reported this through the "report bug" button, but those aren't getting acknowledged, so I'll try here too. (And I note that the bugs/glitches thread seems to have disappeared).
I think there is a problem if the game opens a window while you are moving items in backpack/storage/stash. When this happens, I find that the item I'm moving gets stuck to the mouse-cursor and prevents me doing anything: I can't put the time back; I can't put it into a new spot; I can't choose an option on the new window.
I have this a few times. The last one I was rearranging items when a hidden creature kills me and the resurrection window opens and I had to reload the game. The other times I was rearranging items to make space to accept a new one when the time-left-to-decide box opened up; I had to wait until it timed out and automatically discarded the item before I could do anything more. (A bit frustrating when the item was one of the better quest rewards.)
