Delete the LW Prefs do you mean? yes. But 1st make a note of all your LW settings b/c if you trash the prefs you'll need to reset the settings within LW. You have a USB modem. Not always recommended to use USB modems with G4's but if it's working fine for you then fine. Can you do a small test for me: Bug Report instructions & sample image & tell us whether your result is true or false. Also make a quick visit here: http://www.u.arizona.edu/~trw/games/nat_or_not.php & ignore the text in Red box! Just tell me what it says in the grey box area below it (under The Applet.) All you need to tell me is whether it says you use NAT or not. If there's no mention of it then that's fine.
