Well, it's working quite well for me on OS X PPC and Linux AMD-64 with a reasonably recent SVN checkout of numpy. Did you build numpy yourself, or use a binary distribution? Windows? Linux? OS X? Please join us on the numpy mailing list with this information; hopefully there is someone there with a similar platform who can replicate your bug or offer better advice than myself. http://www.scipy.org/Mailing_Lists In the meantime, you might try compiling a recent SVN checkout of numpy and see if the problem goes away for you. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
