Your DropTarget has a code path that doesn't return a drag result:


     def OnDragOver(self, x, y, ref):
         try:
             r = wx.Rect(3,3,165,148)
             if r.InsideXY(x, y):
                 i = ((y-3)/76)*3+(x-3)/55
                 # print x, y, i
                 if self.parent.highlight != i:
                     self.parent.highlight = i
                     self.parent.Refresh()
                 return wx.DragCopy
             else:
                 if self.parent.highlight != None:
                     self.parent.highlight = None
                     self.parent.Refresh()
                 return wx.DragNone            # <== Add this line
         except:
             import traceback
             traceback.print_exc()
             return wx.DragError
