Filr 1.0.1. Windows 7. Edit-in-place. With Office 2010 seems to this functionality does work ok. But using LibreOffice 4.2.4 it does work when file uploaded is accessed firstly, but afterwards does not open anymore this file "Error reading data from Internet. Server error message: 409 Conflict.". Yes, still is possible to download file, but not to edit "directly" from server.
More thanks, Alar.
