[Gvsig_english] Error - Geoprocessing tools

[Lucie Prunarová]

Hi,
unfortunatelly I don't have grass and I don't know which tools it has to
control the topology. Is there something in gvSIG what I can use for the
control? Or sextante? Or can you please check the data for me? It's weard
that the tools work sometimes and sometimes not. If the data would be bad,
I thing that the error should be there everytime.
