I'm administering a local version of JIRA 6.0.1 and Drag and Drop Attachments plugin 2.10. Users are all on Google Chrome 28.0.1500. Some can drag and drop from Windows Explorer fine, and for others the view issues screen will show a bold heading "Uploading Attachments" and nothing will happen. I've waiting overnight, tried it again, but nothing happens. I've tested on other browser but I can't find a consistency... some users can drag and drop from the desktop or explorer and others cannot. Any ideas??
