Michael, would you try the newer driver? http://www.tackymt.homeip.net/~taku/maestro-latest/ -- -|-__ YAMAMOTO, Taku | __ < <taku@tackymt.homeip.net> Post Scriptum to the people who know me as taku@cent.saitama-u.ac.jp: My email address has been changed since April, because I've left the university.
