It's driving me nuts! It seems that whichever way (Natural vs 'Normal') I set up for scrolling, I'm asking for trouble. In Safari, roughly 80% of the time I have to scroll up or down a page I get the spinning beach ball until it decides to jump to where I was trying to scroll to. There's nothing fluid about it at all! Look, we all knew there were going to be a few bugs, but this one makes it infuriating to do simple tasks. In other news, Aperture seems to have suffered a little, especially in Full Screen Mode. Live through it, hope they fix it, I guess.
