While I know that in previous versions of OS X inertial scrolling wasn't supported on my getting-long-in-the-tooth late 2006 Black Macbook Pro, I was using the third party app Smart Scroll to give my machine the inertial scrolling feature (i.e. swipe down the page and scrolling 'slides' the content frame similar to the feel of scrolling/sliding down on an iphone or ipad.) Unfortunately the developers of Smart Scroll haven't updated it to work under Lion yet. However, I notice that tucked away in very preference panels there is both the option to 'reverse scroll' (which I like and have gotten used to) as well as 'inertial scrolling' located (somewhat strangely) in the trackpad settings of the Universal Access control panel. The reverse scroll works fine (and has since 10.6) but checking the 'inertial scrolling' feature doesn't seem to do anything. Can anyone confirm that in Lion inertial scrolling SHOULD work on my late 2006 Macbook? I do wonder if it isn't officially supported by Apple on my older trackpad (two finger scrolling works but other than that no multi-touch gestures) and the 'inertia scrolling' checkbox doesn't do anything? Any ideas? Am I going to have to wait for a third party to provide me with the option..? Thanks in advance for thought and answers.
