i'm having some serious problems with Safari. i have already had to quit it 3 times today because it just wouldn't load web pages. i'm typing this in Opera now... i can open web pages fine when i freshly open Safari, but then if i leave it for about 10 minutes, then come back and want to use it again, it's useless, and so far i haven't been able to access anything if i leave Safari open for more than 10 minutes. i've just got the Security Update 2003-12-05 which is supposed to fix some Safari stuff... but this problem hasn't really started until yesterday. does anyone know what is causing this?
