Hi Nik,

Which gvSIG version are you using?
And also: have you done any reprojection when loading your shp in the 
View. There's a bug regarding this.
More: any internal polygon within your features? It was a bug that has 
just been fixed for next release.
And 'Area units' inside View Properties are set in 'km2'?


Regards,
Sergio
