It keeps giving me the following message:<br class=""><br class="">"The document “...” could not be autosaved. The file has been changed by another application.”<br class=""><br class="">I also get a similar reminder when I ask for explicit save. The file is not open anywhere else with any other application. Is there some setting that I messed up possible? Any suggestions?<br class=""><br class="">Many thanks.<br class=""><br class="">==Tamer<br class="">--<br class="">M.
