<DIV><FONT face=Arial size=2>hi again - thanks for replying - I had a thought
overnight and decided to check the input data by dumping the loaded shapefiles
and its heer the problem lies - the correct number of recorsd are reported in
teh tables and by the loade/dumper but taking the orignal shapefile, loading it
then dumping it to a new shapefile reveals that the .shp itself is funny and
causes the generic 'segmentation violation' in av3.1 and has lots of offshoots
and strange polys in AV8. ive attached a zipfielof teh original shapefile and
the dumped one (nuts2.shp).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I guess its to do with being a multipolygon with
holes and islands but Im not sure how to proceed to get the data loaded properly
???</FONT></DIV>
