Drag and drop in finder stops working
I recently updated to El Capitan on my mid 2012 macbook pro retina. After the updated the drag'n'drop functionality in finder drops out randomly. I can copy and paste with my keyboard, but dragging and dropping files within finder or between finder and other applications doesn't work. This usually happens when my mac has been running for a few days. Logging out and in again solves the problem.
Google searches have all come up emtpy.
Anyone got a clue?
