Apple has released iPhoto 9.1.5, a minor update to its consumer photo management software that addresses several issues. These include the way the date range of an event is displayed after the Adjust Time and Date command has been executed; the fact that some Ken Burns Effect transitions may not play in a saved Classic slideshow; and issues with scrolling, deleting, selecting, and cropping pictures.

Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
