LibreOffice Writer 3.4.0 running under Windows 7 64-bit. Problem 1 reproduction - * Start Writer * Create a document and type in a few words, nothing special or extravagant * Save as an .odt file * Load into MS Office 2010 Error message: The file <filename> cannot be opened because there are problems with the contents. Details The file is corrupt and cannot be opened. Clicking OK asks if you want to recover the contents of the document. The recovered document is correct and uncorrupted. ----- Problem 2 reproduction - * Start Writer * Create another document and type in a few words * Save as a .doc file (97/2000/XP) * Load into MS Office 2010 Red toolbar message: Protected view - Office has detected a problem with this file. Editing it may harm your computer. Click here for details. It is then possible to click "Edit anyway" and get on with things. The loaded file is correct and uncorrupted. --- In the past I've never had problems with basic files working between both word processors, but something has happened which is causing Office 2010 to dislike both the .doc and .odt versions of the files LO is saving. This is not a good thing. I'll refrain from calling it a bug in case there's an option within LO which can save the files in such a way as to pacify Office 2010. Otherwise I can't trust it to be usable in a mixed environment. -- View this message in context: http://nabble.documentfoundation.org/LO-Writer-3-4-0-basic-doc-odt-files-not-understood-properly-by-MS-Office-2010-tp3023234p3023234.html Sent from the Users mailing list archive at Nabble.com. -- Unsubscribe instructions: E-mail to users+help@libreoffice.org In case of problems unsubscribing, write to postmaster@documentfoundation.org Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/www/users/ All messages sent to this list will be publicly archived and cannot be deleted
