I would use Update Column from the Table menu. MI allows you to take data from "hidden" fields and transfer it to viewable columns. These are the same data fields that report the area of a region when you double click on it. I needed to update my parcel table so I went ahead and did this.

Your MI add-on technical support person must have been thinking about ArcView. You're fine in MapInfo. One of the advantages MI has over AV. Will Mitchell GIS Manager The Environmental Company, Inc. 2496 Old Ivy Rd Charlottesville, VA 22905 ph 804.295.4446 fx 804.295.4435 http://www.tecinc.com
