^My apologies I wasn't aware the other forums mentioned were anything to do with this one. However, the reason I did it is because the question I ask is either misunderstood or 'converted' in the minds of the some of the people who choose to answer and in consequence provide no solution hence my annoyance with the person concerned. As one person suggested it is best to contact the author of the video but it has sometimes proved difficult to gain a response. However, I have my reservations about asking questions on this type of forum now for reasons I won't go into.
