[Newbies] Invisible Connectors

I am just starting with Squeak, it is something completely different 
from all other programming languages/environments I saw before. Very 

I am using Squeak 5.2 for Linux (under FreeBSD-12 Linux compatibility 
layer), it works.

Coming to the question. I found this package called Connectors. I tried 
to connect some Morphs with "Curvy Arrow" and it all works fine, 
clicking on the GUI. But, if I try make a connector from the Workspace I 
can't see the line and I don't understand well what happens.

For example, If i run this code
----- https://wiki.squeak.org/squeak/1773 -----

green := Morph new color: Color green;         position: 100 at 200; 
openInWorld. red := Morph new color: Color red; position: 100 at 300; 
openInWorld. c2 := NCAAConnectorMorph new connectStartTo: green ; 
connectFinishTo: red ; openInWorld.


I see the two rectangles but I don't see the connector.

I tried to inspect madly the "c2" object but I can't find how it is 
different from a Curvy Arrow that is actually displayed.

I installed Connectors via SqueakMap, the latest release I saw (I can't 
see the number now, probably because the package is already installed).

Any ideas ?
