Old Jewel Software has released LazyMouse 2.5 (http://www.old-jewel.com), a revision to its Mac OS X (10.5 and higher) utility for saving time dealing with dialog boxes and alerts.
LazyMouse is a Preference Pane that moves the cursor to the default button whenever a dialog box appears on the screen. Version 2.5 adds the ability to show an animation when the cursor is moved. The animation shows a ghosted cursor moving from the original mouse position to the new mouse position.
LazyMouse is Universal Binary so runs natively on both PowerPC and Intel Macs. It costs US$9.95, though version 2.5 is a free update for registered users of version 2.x. A demo is available for download.
