Thanks, I'll try that tomorrow. For now I am happy with Herbert's
solution.

Shouldn't there be a way for a package to specify such preferences
just for itself?

It seems to me, at the moment, that the tooling/infra-structure around
Squeak is more difficult to learn than the language (including the
standard classes) itself. I will struggle on.

Thanks,

Shaun.
