What can I say?
The "Man" comes through again. Bill, that works quite well and is easy to
implement.
Thanks for the insight.

You could reposition points by lowering the coordinate precision,
causing "close" points to snap to common points. Populate two new
fields with x and y coordinates of the objects, but use the
round() function to lower the precision. Of course, you might
want to save the original coordinates too! For example,
longitudes of -105.123456, -105.123458 and -105.123463 all fall
on -105.123460 with Round(fLon, 0.000001), where fLon is any of
those longitude values. Once your points are snapped to the same
locations, Disperse will work on them.
