Though I am not happy to write spaghetti code, I spent yesterday
rewriting my chart button processing so that everything behaves
properly from the user point of view.
I had to first "claim the mouse" for a button array area in the top
to bottom Z order of these draggable buttons, then process and draw
the button/information arrays in the opposite (bottom to top) Z
order. Not happy to code this way, but moving on to the next problems.
If and when we get drawing in layers I will gladly rewrite this area.
BR,
Dennis
