Subject Re: Inter-cell lines no longer "spurious" pdf viewer problem? RESOLVED
Date Fri, 09 Nov 2012 00:19:58 GMT

black which somehow seeped through in Evince and for the print shop.

Thanks for your efforts.  I think there is an issue, but whose it is is 
not clear to me and we think we're past the pain point.
