Hello Eiffel users,
 I set up a class(see below) to display a segment in a window on the screen.
When I execute the class the window appears but the segment will not appear 
unless i resize the window manually. Does anybody know why this is so??

	class elem_graphics              	--run under OpenWindows2.0
	inherit
		graph_window;
		dev_const;
	feature
		Create is
		local
			p1,p2:point;
			s:segment;
		do
			initialise;
			p1.Create(50.0,50.0);
			p2.Create(100.0,100.0);
			s.Create(p1,p2);
			s.attach(my_world);
			s.show;
			windy.show;
			windy.display;
			my_world.display(windy);
			gas.execute;
			rescue;
			on_device.close;
		end;
		my_world:world;
		windy:graph_window;
	
		initialise is
		do
			my_world.Create(1.0);
			windy.Create;
			windy.size_pixel(800,800);
			visible:=true;
			visibility_changed:=true;
			windy.set_border_width(5);
			windy.cover(800.0,800.0);
			windy.associate(my_world);
		end;
	end;

Please e-mail any info that might help.

Thanks in advance,
