The immediate effect is that everything is bigger and the chart
overflows both margins. The text is at normal size for this
document. So the text problem was solved, but how to get the
widgets and the spaces between them down to a reasonable size?
After much experimentation I came up with this:

\setupFLOWcharts
[
nx=6,
ny=2,
dx=\bodyfontsize,
dy=\bodyfontsize,
width=.15\hsize,
height=.15\hsize,
]
There is still some overflow into the margins and some of the text
is too highly hyphenated. But at least I am on the right track.

When all this is over I may write my own version of the manual
so I won't forget between uses :<) 

Thanks much,
