If the document has been going back and forth between LibreOffice and Apache OpenOffice (or old OpenOffice.org) it is quite possible that it was corrupted at some stage (I have a document where this happened...) If your father has been using OpenOffice only, can he pinpoint a version where it worked/works correctly? Does he have older copies of the document (it might have become corrupted at same point in the past...) In any case, the easiest way to try earlier versions of LibreOffice and OpenOffice (assuming he is using Windows) is to get Portable versions http://sourceforge.net/projects/winpenpack/files/X-LibreOffice/releases/ http://sourceforge.net/projects/winpenpack/files/X-ApacheOpenOffice/releases/ http://sourceforge.net/projects/winpenpack/files/X-OpenOffice.org/releases/ Hope this helps... -- View this message in context: http://nabble.documentfoundation.org/Question-about-Calc-and-hiding-rows-tp4118694p4118754.html Sent from the Users mailing list archive at Nabble.com. -- To unsubscribe e-mail to: users+unsubscribe@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
