(I found the workaround.) Here is a complete example. Please load the attached poset with P=load("poset.sobj") (there is nothing secret about it, but I found it easier to store it that way) Then do ppPoset(P). The size of the graphs does not seem to be taken into account by the poset layout algorithm...
