Question: Dragging a file and dropping it on the Desktop icon of the left Finder bar
When I try to move a file by dragging and dropping it on the Desktop icon of the left Finder bar, it disappears, even though when I hold it there for a second, it blinks and places the file there, but then immediately the file disappears.
At first I thought it was mistakenly put somewhere else, but when I search for it, it is nowhere to be found.
Has this happened to anyone?
Mac Pro, OS X El Capitan (10.11.6)
