line drawing errors

Usually this is caused by drawing line shapefiles as TYPE POLYLINE instead of 
LINE. Polygons and polylines are forced to have the first point be the same as the
last point. This is carryover from the ESRI shapefile spec. Can you check the
map file you're using? Newish versions of the code catch this condition as an
error.

Has anyone noticed line drawing errors with mapserver 3.01 on NT.  Sometimes
there is an extra segment drawn connecting the beginning and end points of
lines. I put a image on my website at
