Hi all Recently I have been having this issue where when you try to drag and drop, the file (or folder) can be dragged, but it simply would not drop to the new location when you let go of the mouse. The file (or folder) being dragged stays with the curers and it would not disappear! At the moment, the only fix for me is to put my computer to sleep and wake it up again, but this is starting to get to me as this is only a temporary fix! Some apple forum suggest that it could relate to either AirDisplay or AirParrot, but I do not have any of these programs. Computer spec is as follows; iMac OS X, Mid 2011, V10.9.5, i5 2.5GHz, 20GB DDR3. Any help would be much appreciated!
