Re: Is there confliction between "gsnContourZeroLineThicknessF" and "gsnContourZeroLineThicknessF" when panel the contour maps in NCL5.2.1?

Hi Li,

Thanks for providing the script and data up front.

There's something very strange happening with your script. I'll take a look at it more this afternoon. You are right: there is a difference between 5.2.0 and 5.2.1, but I don't know yet what change we made that would cause this.
