Although the basic interface unfortunately remains the same, Skype has released Skype 5.2. The latest release of the Internet telephony software introduces a new view that enables you to see and control video calls even when you switch away from the Skype app. Skype Premium subscribers can also share screens with a group, rather than just one-to-one. The company has also added support for the HD cameras that come built into newer Macs, as well as Logitech’s B910 HD camera. A number of unspecified bug fixes round up the release, although several known issues remain, including a crash when changing your password, problems starting screen sharing when the remote party does not send video, and no keyboard support for dialing when using Mac OS X 10.5 Leopard. Also, although Skype 5 features automatic updates, for at least one of us, the automatic update failed, forcing a manual download and install. (Free, 20.8 MB, release notes)
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.
