I know I can throw away Extentions and the machine will rewrite them on startup. Can I do that to Preferences? Norton says the Sound Preference is bad on a G3 I have running OS8 (don't say it). Also, as an aside, the same machine crashes when I go to the Chooser and try and load other machines on the network. I get around this by placing aliases on the machine from other machines which can connect to it.
