Ok, sometime last week I got a pop-up that Safari Beta had expired. Uh, ok. So I went via Software Update and again re-downloaded Safari. Ever since then I am having problems. It unexpectedly quits trying to get to some pages, load times on some pages are EXTREMELY long--end up not loading, and when I try to log-in to Yahoo! it gives me the runaround. Safari was working FINE before. What gives!?
