I've been using this for years and years with never a hiccup and the same can be said of this release. It's one of those progs that you can't imagine using your computer without, and functionality that Apple should have included from the very start (especially if you use a two-button mouse or control-click a lot). Give it a try after reading the simple directions, and you'll be wondering how you've managed to get along without it. Stable, easy, simple, and extremely time-saving features.
