I'm on =release_8.0-pre-181-ge7cfb4= and with =C-e o o=, LibreOffice immediately opens the file. I'd expect this with =C-e o O=, but not with =C-e o o=.
I noticed that I have an openwith process running =soffice /path/to/file.odt=... is the exporter somehow triggering openwith to open it even though I haven't said to do so upon export? Here's my settings in .emacs: (openwith-associations (quote (("\\.pdf\\'" "evince" (file)) ("\\.mp3\\'" "vlc" (file)) ("\\.\\(?:mpe?g\\|avi\\|wmv\\|mov\\)\\'" "vlc" ("-idx" file)) ("\\.\\(?:jp?g\\|png\\)\\'" "geeqie" (file)) ("\\.\\(?:odg\\|odt\\|docx\\|doc\\)\\'" "soffice" (file)) ("\\.\\(?:odp\\|ppt\\|pptx\\)\\'" "soffice" (file)) ("\\.\\(?:xls\\|xlsx\\|ods\\)\\'" "soffice" (file))))) John
