I just installed Panther (a clean install), and it works nicely, except that when I press one of the Exposé keys (F9, F10, F11), it just beeps and doesn't exhibit the expected Exposé behavior. If I change the shortcut key to alt, shift, control or command, those work, as do the hotspots. However, I use all the other keys and I don't particular care for hotspots. Personally, I'd prefer to use F9 through F11. Am I missing something obvious?
