I've got one even better. I get the attached error message with every version of Mozilla and Netscape for OS X that I have installed. Subsequently, Mozilla and Netscape spiratically loose all or parts of my custom preferences once I quit the application. I'm pretty sure the two are related, this is one of the reasons why I've abandoned Netscape for IE when I'm using OS X. The other reason, would be the slow response of Netscape/Mozilla under OS X as compared to IE and other OS X browsers. I had been a loyal Netscape user, but with the recent versions of Netscape, I've been draw away to use other browsers. I wish they would go back to Netscape 4.7 and start over. Netscape 4.7 was the last Netscape version that was truely robust with a quick reponse. It would be great if someone would port Netscape 4.7 to OS X, I would definitely start using Netscape again then.
