Hi AJ,

I've found that the world.shp file from
http://aprsworld.net/gisdata/world/
tends to bust iMap in certain situations, whereas the cntry02.shp file
that
comes with the IDL distribution,
C:\RSI\IDL61\resource\maps\shape\cntry02.shp,
works OK. Apart from the gisdata file being 2MB larger, do you know
what the difference between the two files is?
