This generic control property has been replaced by four new properties specific to ThumbnailXpress that allow a finer granularity of control over the types of drag/drop operations the control will allow. The new properties are: IntraComponentThumbnailDragDropEnabled, InterComponentThumbnailDragDropEnabled, EnableAsDragSourceForExternalDragDrop, and EnableAsDropTargetForExternalDragDrop
