Hi Dmitry, I happened to notice 2 URLs in the second line of a gnumeric work book do not exist. They are http://www.gnumeric.org/v10.dtd and http://www.gnumeric.org/v9.xsd You can see this is so by using the attached file "bug.gnumeric" as follows $zcat bug.gnumeric | sed -n 2p I imagine several fixes. 1.) Add the pages to www.gnumeric.org. 2.) Delete the second line of the workbook's XML. 3.) Put working URLs in the second line of the workbook's XML. Thanks again! Kingsley
