Try cleaning your keyboard. My old Mac did this when I spilled coffee on the keyboard.

Check the settings in your keyboard control panel. Apple>Control Panels>Keyboard.
Pressing command-space rotates the keyboard layout, maybe that’s what caused this?

BTW, why are you still using OS9? Tiger comes out next week!
