Tabledrag in Drupal 7 admin pages only working in Firefox For some reason, in the last couple of days any table that is tabledrag enabled (in core admin interfaces like the menu editor, as well as custom modules) only works in Firefox.

In IE and Chrome there are no errors reported in the console, the row is highlighted on mousedown, but nothing happens when you drag.

Has anyone else encountered this and know of a fix?
There was a regression introduced in 7.52 related to dragging in the admin interface. It's fixed in the 7.53 release. It may be as simple as upgrading to the latest version of core.
