Two nights ago my laptop had a head crash. Disk drive utterly gone. My last viable backup was a fortnight (and a bit) ago. Damn. If you sent me *anything* in April, please re-send. Sorry about the inconvenience. Regards Peter Miller <millerp at canb.auug.org.au> /\/\* http://www.canb.auug.org.au/~millerp/
