yeah thanks for the quick and witty replys about the users manual, which I would have consulted first, if I had one! But I havn't, and no one seems willing to lend me one. As for using the search facility, you will not often see me post pointless question on ANY forum as I always use the search, and browse through other posts on the forum looking for advice long before I post a question that has been asked and answered many times in the past. However, on this occasion, the search did not provide the answers I was looking for, hence me asking the question.
