// Documentation:
// This script exposes two global variables, Draggable and Droppable. To make an
// element draggable, simply call `Draggable(element)`. This sets the necessary
// CSS properties and event handlers. It also overrides the addEventListener and
// and attachEvent methods (if present) to include the following events:
// onstart (When the element begins dragging)
// ondrag (When the element is being dragged)
// onstop (When the element has stopped dragging)
// You may also assign element.onstart, element.ondrag, and element.onstart to
// add event listeners.
// Lastly, if you need to physically prevent an element from dragging, you may
// call event.preventDefault() from within the onstart handler.
//
// To make an element droppable (have things dragged onto it), call
// `Droppable(element)`. This sets the necessary event handlers and coordinate
// searches. Once again, it overrides addEventListener and attachEvent to
// include the following events:
// onhover (When another element has been dragged over the element)
// ondrop (When another element has been dropped onto the element)
// onunhover (When another element has been dragged off the element)
// As before, you may also set element.onhover, element.ondrop, and
// element.onunhover directly.
// To remove all drop points from the current session, call `Droppable.reset()`.
//
// The event object is also extended with the following properties:
// dragTarget (The element being dragged)
// dropTarget (The element being dropped onto)
//
// Known bugs:
// * removeEventListener and detachEvent do not work with the custom events.
// Workaround: Use direct assignment (element.onevent) instead.
// * There is no way to remove a single drop point.
// Workaround: Call Droppable.reset(), then reinitialize the other drop points.
// * There is no way to remove dragging from an element.
// Workaround: element.onstart = function(event) { event.preventDefault() }
// * Changing position of droppable elements after initialization breaks drop
// Workaround: Static droppables are much faster than moving ones. Either call
// Droppable.reset() and reinitialize often, or ask the author to modify the
// script to account for this (and accept the resulting slowdown)

Is there anyone who can fix it up for use with VB 3.8.4? Overall point to this is no drag = no text selection/no text selection = less posts being copied!
