Hi, Listers, There was a question (from Mary Kay) if I was ok. Yes I am relatively ok. I have been talking to a few people off list, I have been working on another project lately that takes a lot of time, and I have been "half sick" since Christmas and so haven't felt like doing anything extra. Nothing serious. Thank you all for being concerned. I didn't get your message, Mary Kay, and couldn't find it in the archives. So would you try again. A while back I found that some of my messages were being screened out by my "over-enthusiastic" server trying to cut down on spam. Maybe that's what happened. If anyone asks me a question, I intend to answer all- in some way. if you expect an answer and don't get one very soon, please send it again. Best regards to all of you. Chas
