Subject Re: Inter-cell lines no longer "spurious" pdf viewer problem? RESOLVED
Date Thu, 08 Nov 2012 22:28:51 GMT
When I reviewed sidebar.fo, I completely neglected the colours and 
borders added for debug purposes (oh so long ago). Let me get you a 
clean version.  The "spurious lines" appear in the column which is not 
spanned by the "inner" cell in the first row.
