Thanks... I'll try the recipe on the PB and if that doesn't work I'll mix in hops and water - at the very least I'll have some homebrew ;)
Update to this problem. When I rebooted the PB last night the USB ports had "changed sides" - the one that was working now didn't, the one that wasn't...
Ran the software update on 15"PB1.67 - Everything is fine... except... 1 USB port has simply stopped working. I had a hub connected to it and everything attached stopped responding after the reboot. Plugged it into the other USB port and everything works fine.

I think this is a networking problem.
I was happily sharing a cable internet connection from an airport express to two macs - iMac running osx10.4 and powerbook running tiger.
I bought a new airport extreme basestation (to extend the range).
Plugged it in, configured it as the main base...
