I've got a 12-inch powerbook. Two finger scrolling on the track-pad works great, except for one spot: on the NY Times front-page (nytimes.com) there's a window toward the bottom where video clips are displayed. Note that I'm not starting the video -- just going over the window where it would be displayed. In Safari I scroll down into that window, using two fingers Suddenly down-scrolling stops working. Curiously, up-scrolling still works I can navigate out of the window using one-finger and now down-scrolling works again. By the way, if I scroll through the window before the (still)image in it loads, there's no problem. I haven't seen this anywhere else. Is it just me, or does anyone else have this oddity. edit: ok, I get exactly the same behavior with the scroll wheel on my Logitech mouse on my PowerMac.
