Why is drag and drop feature not working?
On the course settings page I am trying to drag/drop multiple PDF files to upload as Resources to the course. Each time I attempt the drag/drop, the ACP window closes. I had to upload the files one by one. And, even with that process/(those steps); once the PDF is uploaded I have to refresh the window, after Saving, to get the "click to upload" button to re-appear.
