Sorry I haven't been more active in responding but you have to understand that I try to drop in here when I get a minute of free time. Right now it's 6 PM on a Friday night and that's the first free time I've had all week. In other words, I just can't respond to all your queries and there's no one else here who can. Take that as an apology if you wish. I just want you to know that I do scan the threads and it's not like they're not being read. It's just that there isn't time to respond.
