We extend our previous analysis of the unitarized pion-nucleon scatteringamplitude including up to fourth order terms in Heavy Baryon ChiralPerturbation Theory. We pay special attention to the stability of the generatedDelta(1232 resonance, the convergence problems and the power counting of thechiral parameters.Comment: 9 pages, 4 figure
