I ment well with my comment, and request, and I guess I must assume you did too, BPtoo. This medium is new to me and difficult (misunderstandings seem at least as likely as not). This particular subject and the approaches to its treatment are as well with at least one fierce controversy involved. I'm a bit taken aback by your response that doesn't seem to answer my request but instead imply something else. Perhaps I'll come to understand better. My sincere apologies if I've offended, a phrase I have a nasty feeling I'm going to get to use far to often on this forum if I manage to mesh here for long at all. -dsl
