A small gripe with an otherwise perfect machine:

Is there any convention in the software to
disable or 'lock' the contrast wheel? If
not, is that something that could be built into
future OS versions?

I seem to have developed the nasty habit of
frequently nudging contrast by accident, when
handling Pronto.

I wonder why they didn't use software contrast
control rather than the wheel, I find the
wheel not recessed enough, even two tiny
push buttons would be better I think. Maybe
that will be addressed in future 'redesigns'
of Pronto.

Herr Schultz, Herr Helpful?

Thx for any insight!
