Option + Spacebar no longer creates a non-breaking space
This seems utterly whacked to me, but all of a sudden the key combination of the option key + spacebar does not create a non-breaking space in any word processing application where just a day ago it did. Word, Nisus Writer Pro, Scrivener. Type that combination of keys and nothing at all happens. Since it is consistently malfunctioning across apps, I have to assume it's something in the OS.
I've run permissions repair, I've logged out. I've shut down and rebooted. I've combed through the keyboard shortcuts. But the option key has stopped working in combination with the spacebar. Yet just to check that I'm not dealing merely with a dead key, Option + Command + Spacebar does bring up the Spotlight window, so in that respect it's still recognized.
