Lynn,

I don't think VS controls exposure time on Scanwits directly - they have an
autoexposure system with "no" manual control. However, I agree it appears
something Ed is doing appears to result in longer exposures. It would be
interesting to know how this happens - maybe Ed could jump in with a
theory/explanation?
