Okay, that makes sense. My hosting company (telivo.com), referred me to the external link I posted:
http://dev.mysql.com/doc/refman/5.0/en/old-client.html
and said it was something I could resolve with the config file. They have been hugely unhelpful up to now, so it does not surprise me that they have given me bad advice. So I suppose my next question is whether I can resolve this at all without action from telivo?
