Hi Curry
Thanks. I thought this would be cool to play around with one day but I would
never remember where I saw it. This will help an old brain.
It would make also make a good LiveCode Lesson. Once Alex figures it all out
and has it all working they can document the process and submit it as a
LiveCode Lesson and thereby gain instant fame and fortune ... well at least the
gratitude of those who follow afterward… maybe even themselves (see more in my
next email “Communication with future you with a message board”.)
