Hi Luca, I have had a few people report this issue occurring intermittently but have never been able to narrow down a particular cause. In most cases, quitting the application and re-opening it has then allowed the drag and drop to work correctly. Can you try that and see if it works for you? Otherwise, can you let me know details of your OS etc. and whether there are any particular steps you are following which trigger the behaviour (I would love to get steps to reproduce this so I can diagnose and fix the issue!) Matt
For me (Mac OS X 10.11.4) dragging an item doesn't _look_ like it's doing anything, but when the cursor gets over a target field the field highlights, & if you drop then, the item is moved. The bug is a lack of a visual cue that something is being dragged.
Now it is the same for me. If I drag I don't see anything, but when I move the cursor on the target field it works. But I just upgraded my version, I don't know if before the upgrade it was the same.. Thanks Luca
Identical issue here using OSX 10.10.5. The 'Other' items highlight but are unable to be dragged and restarting does not help.
