Since installing Safari 5, I encounter the spinning beach ball when I try to scroll down a webpage or scroll between tabs. It appears that I cannot scroll/switch until the webpage is fully loaded. This is extremely annoying because when my gestures are finally registered, Safari goes wacko trying to catch up with the previous gestures/commands. For example, if I use a swipe gesture to navigate between tabs, when Safari becomes responsive again, it will register all previous swipes and rotate between tabs until it 'catches up'. I hope that makes sense. When I use Firefox, there is a slight lag, but I'm still able to scroll with only slight choppiness. By contrast, Safari 5 literally freezes for about 5 seconds. As a benchmark, I tried using both browsers while loading www.interfacelift.com. Firefox worked fine, Safari 5 was crippled. Any ideas/suggestions? I try to keep my system organized/up to date, so I have no idea what may be causing this.
