OK, well I'm having a very troubling problem with Safari on my RevD 12" Powerbook (10.4.1). This started just a few days ago. Whenever I try to browse a web page (any page), it will load 70-80% of the page and hang. Sometimes clicking the X and then the refresh symbol will get it to work. Other times, it just doesn't. I haven't installed any software in weeks. Anyone else have this problem or know how to fix it? Is it possible to re-install just Safari? Thanks!
