Thanks for the info.
I don't blame you for your impatience, I guard my time also by necessity. Before posting (1st time on a forum) I read the admonitions, read the guides, and did do searches. I read thru pages and pages of threads with no useful info (often the search phrase used but no explanation). Probably means I need to learn how to search more effectively. After searching, I read posts with likely Subject lines- found only 2 with some useful info. I'm yada yada-ing you just to give feedback from the point of a rookie, which every user is at least once. Things apparent to an experienced person often are not obvious to a rookie. As a design engineer with 30 years experience designing, documenting projects and publishing articles, the best but toughest thing to do is put yourself in the place of the reader who doesn't know the details like you do. It's especially tough to do when you are time limited. This is NOT meant to be a lecture, just some feedback. Feel free to ignore, delete this post, throw rocks or make fun of me.
I think the answer is implied, but please answer directly: Any potential layer break points listed, ARE valid break points.
I'm still a dumb rookie, but you guys have made me smarter- thanks.
Blutach, you should expect dumb questions from someone in the Northern Hemisphere where toilet water swirls in the wrong direction when flushed.
