Logitech PageScan Color software must have the same problem then. It is
win-32 code that aceesses the parallell port, it does not run under NT,
there is no NT version of the software. It used to run with some
unrelated problems under wine.
I assume that there is a "deep" reason why win9* compatibility has been
dropped here?
