Thanks Hugh

I always wished that there was some LiveCode example stacks which showed
proper design and procedure for different platforms. Like you said, a
documentation so that people like me wouldn't be doing it wrong for years
and years.

And I use Parallels and run Windows lots of time so I thought that colored
spinning beachball just meant I was running Windows.
