just been checking back on forum. Yes I posted the question, did'nt know it was obligatory to reply to any though. Only asked the question. For your information, have had a couple of deaths in the family and another terminal, so have had other things on my mind instead!!! Just because you ask the question does'nt always mean that you want to get into correspondence with the people who answer. And not just because you have not had the reply you want either. Also, am not on the internet constantly to see what people have written. So your comment is noted, but sometimes other things take over!!
