So although an address is stamped on the card, the system reports a different one. (Don't know why this is done, and it seems to make little sense as it could cause a conflict?) -- Paul DuBois dubois@primate.wisc.edu Home page: http://www.primate.wisc.edu/people/dubois Software: http://www.primate.wisc.edu/software
