The only thing it doesn't do that I really miss from Mouseworks is my pop-up menu of shortcuts and keystrokes. All of the buttons are programmable with different kind of clicks, including launching files or apps. It is shareware, $20, but it is cheaper than a new multi-button trackball mouse. I have an older Kensington Expert Mose Pro and Trackball does not work on it. work in Lion, and allows me to set the buttons and scrolling on the new trackball as much as I need to at least.

But, on the Kensington web site, I downloaded a TrackballWorks controller, and that.does. The included MouseWorks installer also failed to work in Lion. My old trackball happens to have just failed today, so I bought a new Expert Mouse (model 64325) to replace it. I recently upgraded to Lion, and indeed the old MouseWorks control panel wouldn't work, nor will any Mouseworks downloadable that I could find on their site.
