We got an iMac 1.5yrs ago and this has been driving me nuts ever since...a brief description: Say I'm at the top of a page and then click a new link. The new page loads. I decide to click the "back" button to return to previous page. The previous page loads. I start scrolling down...maybe I get halfway down the page in 2-3 seconds. then ***BOOM*** Safari decides to catch up, and automatically returns the scroll tab at the right to the top of the page, interupting whatever I'm reading and forcing me to rescroll down. Is this some setting that can be changed?
