pw.mac bug fixes



I still don't have a website for this.  I zipped it up and attached it since when zipped up it is only 10.7 kilobytes.  Since this program works now and the integrator and pwsimp have input validation now so they will not produce wrong results for unsupported expression types, is there any chance this will make it to cvs?  Is there something more I should do?  I have no rights to upload with my sourceforge account.
