Known issues from previous releases:

Drupal 7.51 causes drag-and-drop functionality in Drupal to stop working for certain Chrome, Internet Explorer 11 and Edge users on sites which updated to a jQuery version between 1.7 and 1.11.0 (for example as obtained via the jQuery Update module). See the issue for more details. To solve this problem, update to Drupal 7.53. (Switching to a different jQuery version will also fix the problem.)
