Sigh. It turns out that the Post Office added another ZIP code to our area shortly before we moved. Of course, no one told us about this, and we didn't notice right away. If you have our address in a database, the correct ZIP code is 98056. Sorry for the trouble.
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.
