I think you can just do

	  gtk_signal_connect(GTK_OBJECT(main_w), "destroy",
				GTK_SIGNAL_FUNC(destroy_new_window), DataPtr);

and then have "destroy_new_window()" do:

	static void
	destroy_new_window(GtkObject *object, gpointer user_data)
	{
	  struct PacketWinData *DataPtr = user_data;

	  detail_windows = g_list_remove(detail_windows, DataPtr);
	  proto_tree_free(DataPtr->protocol_tree);
	  g_free(DataPtr->pd);
	  g_free(DataPtr);
	}

so that when a packet view popup window gets destroyed, the
PacketWinData structure that keeps track of it is removed from the list
of packet view popup windows and then destroyed.
