This is a bug bear of mine. Everytime I do another Linux installation I have to try and figure out how to get the spell checking working, with so much out of date advice out there it is sometime frustratingly painful. I have today fixed the spell checking problem again, and since I have found a good web page that seems to be relevant to most recent versions of Openoffice I have decided to link them here for future reference and in case some other poor soul is struggling with this issue.
