lfc84 cheers for that although the link you provided was broken but it did point me in the right direction. After trawling through what I can only say was mostly drivel I found the question

I still can't see what prompted the question and the answer is somewhat patronising but I guess that's how our MHKs work...
Nothing to worry about then.
