POLYCONTOUR procedure [message #488]

I have been using the POLYCONTOUR procedure to shade contours. In certain
instances, the shading extends outside the outermost contour and connects
to another nearby, but separate, contour. Other than these connections the
shading stays within the prescribed boundaries. All of these contours are
closed, so the problem has nothing to do with POLYCONTOUR's inability to
shade open contours. I suspect it is a bug in, or limitation of, the
procedure and not its misuse on my part.

Here is a typical sequence of operations:
IDL> ; Save contours in file:
IDL> contour,jz,jpxd,jpyd,lev=jlv,/xst,/yst,path='cntr.tmp'
IDL> ; Shade contours:
IDL> polycontour,'cntr.tmp',col=replicate(150,5)
IDL> ; Overplot contours:
IDL> contour,jz,jpxd,jpyd,lev=jlv,/xst,/yst,path='cntr.tmp',/noer ase

Has anyone else encountered this problem? Does anyone know how to fix it?
Any help would be appreciated.

Thanks,
Jeff
