Thanks Lodewijk. Great to have your tip. Btw, I tried to answer yr PM but there is no button to click on to do just that and I noticed that yr message was not completed either as opposed to what I could read in the default email reply I received. I have no idea how this works in this forum, pls advise. That is the reason I thought I'd better send a PM to you to thank you this way. I hope I did not break any forum rules or restriction through this approach. The more I read the varying posts, I noticed that this is a forum of young men and perhaps in their late teens. I'm getting to feel out of place already...:# I'm 59 years this year. Thanks again and cheersch to you.
