Netflix has finally provided their own drag-and-drop capability on their Queue page. If you have this enabled, it will interfere with the queue manager. Greasemonkey users of the Netflix Queue Manager script should disable the greasemonkey script if they prefer the new Netflix page. If you wish to continue using the Queue Manager script you can disable the new Netflix feature. Simply access your Account Options page and make sure the “Enable drag and drop in the Queue” option is unchecked.
The standard Netflix queue still lacks any sorting or randomizing capabilities.
