When plotting a contour map, with multiple maps on a page, and overlaying
contour plots, and sending output to a postscript file, plotting will halt with
'method="edge"' for contours that appear to be nearly
vertical.  Unfortunately I
cannot reproduce the problem using a simple code snippet, but will send code and
datafile that are creating problem to anyone interested.
