I searched both here and at the Apple discussion forums and couldn't find anyone who had posted about this. Almost every time I am typing something in Safari, the text cursor randomly jumps to the end of the line. There doesn't seem to be any pattern to it. No, I am not touching the trackpad, and I also turned off "tap to click" to make sure that wasn't it. I also tried creating a new, fresh user account and it still does this. It doesn't happen all the time, but it does happen quite often. Has anyone heard of this? Like I said, it only started today. I'm on 10.5.1 and haven't installed anything recently.
