Well, I took the plunge and updated to 10.4.1. iScroll2 works great on my Rev. A Lunchtraydeluxe (17-inch PBG4). For those of you interested in system compatibility, this is cut from the MacUpdate description: > iScroll2 is a modified trackpad driver that adds two-finger > scrolling capabilities to supported pre-2005 PowerBooks and iBooks > on OS X 10.3. Supported models include aluminum PowerBooks > introduced from 2003 to 2004 as well as all G4 iBooks. It's especially nice since I figured out how to two-finger scroll properly after reading the MacOSXHint about it. I was so used to fn- trackpad with uControl that I was using both hands to do the scrolling with iScroll2, resulting in very rough and unpredictable scrolling behavior (holding finger down from left hand and sliding up/ down with finger from right hand).
