Mac OS X 10.4 (Japanese): Spotlight search field unexpectedly opens with Command-Space key combination

Issue or symptom

In the Japanese language version of Mac OS X 10.4, the Command-Space key combination should switch the Kotoeri input source. However, after some installations of Mac OS X 10.4, the Command-Space key combination may open Spotlight instead of switching the input source.

Solution

Follow these steps to restore the Mac OS X 10.4 Tiger (Japanese language version) default keyboard shortcuts (which are: Command-Space to select the previous input source, and Control-Space to open Spotlight's search field).

1. From the Apple menu, choose System Preferences.
2. From the View menu, choose Keyboard & Mouse.
3. Click Keyboard Shortcuts.
4. Click the Restore Defaults button.
5. Close System Preferences.

Additional information

This may occur when if you upgrade from Mac OS X 10.2.8 to Mac OS X 10.4 via an Archive and Install installation. Or, this may occur when you transfer data from Mac OS X 10.2.8 or earlier using Mac OS X 10.4's Migration Assistant.
