Will do. I sent an email in to Codename One support with 2 more comparison pictures and my hypothesis about the initial size of the Windows JFrame affecting the SpanLabels, layout managers and icons. I asked Lianna to send it to you and Steve. The biggest question for me is why the size of the macOS javase JFrame is of a sufficient size to define a solid foundation for the measurements, and the Windows build JFrame from the same code starts out at 1/3 the size.
