One thing that annoys many Lion users is “rubber-band scrolling”: When you scroll to the end of a page in many apps, the page seems to continue scrolling a bit, then bounces back. OS X Hints reader Havner found a way to remove this effect.
As with so many other ‘hidden’ settings in OS X, the fix for this is just a Terminal command away:
defaults write -g NSScrollViewRubberbanding -int 0
In Terminal, enter that command then press Return. It should stop the behaviour in the Finder, Mail, Preview and TextEdit, among other applications; it does not, however, work universally, Safari being one notable exception.
If you want to revert to the standard bouncy behaviour, just run this command in Terminal:
defaults delete -g NSScrollViewRubberbanding
In both cases, you’ll need to quit and relaunch any applications that displayed the rubber-band effect. If you find that this works with more than the applications listed above, post your success stories in the comments below.
