      Description

      It is not possible to drag and drop items between two full listboxes. Seems to be a bug.
      It also happens intermittently between one full listbox and one partially filled listbox.

      I have tested this code in ZK Sandbox, so it is reproducible.

      <window title="Listbox" border="normal">
      <hbox>
      <listbox onDrop="move(event.dragged)" droppable="true" fixedLayout="true" rows="3">
      <listitem label="1" draggable="true" droppable="true"/>
      <listitem label="2" draggable="true" droppable="true"/>
      <listitem label="3" draggable="true" droppable="true"/>
      <listitem label="4" draggable="true" droppable="true"/>
      </listbox>
      <listbox onDrop="move(event.dragged)" droppable="true" fixedLayout="true" rows="3">
      <listitem label="5" draggable="true" droppable="true"/>
      <listitem label="6" draggable="true" droppable="true"/>
      <listitem label="7" draggable="true" droppable="true"/>
      <listitem label="8" draggable="true" droppable="true"/>
      </listbox>
      </hbox>
      <zscript>
      void move(Component dragged) {
      if (self instanceof Listitem)

      { self.parent.insertBefore(dragged, self); } else { self.appendChild(dragged); }
      }
      </zscript>
      </window>


      If the number of rows is changed to more than 4 then drag and drop works again.

      <window title="Listbox" border="normal">
      <hbox>
      <listbox onDrop="move(event.dragged)" droppable="true" fixedLayout="true" rows="6">
      <listitem label="1" draggable="true" droppable="true"/>
      <listitem label="2" draggable="true" droppable="true"/>
      <listitem label="3" draggable="true" droppable="true"/>
      <listitem label="4" draggable="true" droppable="true"/>

      </listbox>
      <listbox onDrop="move(event.dragged)" droppable="true" fixedLayout="true" rows="6">
      <listitem label="5" draggable="true" droppable="true"/>
      <listitem label="6" draggable="true" droppable="true"/>
      <listitem label="7" draggable="true" droppable="true"/>
      <listitem label="8" draggable="true" droppable="true"/>

      </listbox>
      </hbox>
      <zscript>
      void move(Component dragged) {
      if (self instanceof Listitem) { self.parent.insertBefore(dragged, self); }

      else

      { self.appendChild(dragged); }


      }
      </zscript>
      </window>
