  Hello!

  I am trying again the snapscan backend with the 1236S.
  With xsane-0.75, xsane crashs after previewing.
  With xscanimage I can scan in greyscale but in colors the transfered data are
  not the same at each try. (one time I can see something but the image was in
  few bands...)

  I tried with the backends 1.0.4 + patch "01-transparency.patch" (see mailling
  list last month) and with the snapshot snapscan-20010411.
  Is the problem in the pipe?
