Jim,
     In many .shp files, the attribute format (.dbf) and index format (.shx) 
are included. They can also be separated. Those shp files you were loading into 
the IDV obviously have separated style.

This likely be a bug in the IDV, I still try to rule out the possibility of the 
precision of the data itself.

IDV 2.9 and 3.0 should behavior the same. There is no changes since 2.8 in this 
portion of the source code. I figure out the problme,  the IDV tried to write a 
file named doc.xml in the location it has no permission. I will check in a fix 
soon.

I will give it a try.
