Message Sometimes in ArcView 9.3 when I attempt to calculate the area (in hectares) of polygons in a layer - using 'calculate geometry' in the attributes table - the area is returned but it is less than the actual area by a factor of 1 million. The data view and layer are both in a UTM coordinate system (Map Grid of Australia, GDA94). Has anyone had the same problem?

Message Hi,

There was a bug for this fixed in 9.3 SP1, NIM036694. Have you installed SP1 yet?

Message Hi Melita, thanks for posting the comment. Service Pack 1 hadn't been installed. It is now installed and the problem is fixed.
