LibreOffice froze on me, was non responding. I Force Quit it, but though it seemed to quit it didn’t. Nothing happens when I click on it in the dock, and when I go to restart or shutdown, it says I cannot because LibreOffice is open. ?!
May be How to View and Kill Processes Using the Terminal in Mac OS X - ChrisWrites.com -or similar internet sites related to kill hanging processes - could help.
Thanks for this. I investigated, but according to the terminal, LibreOffice isn’t running either. Still, when I go to the Finder to force quit, it IS there, but I can’t quit it. Maybe I just never shut down my cpu again?
