os x forgetting expose keys

[excalibur313]

I have a macbook pro with the latest version of 10.5. I've noticed recently that os x keeps forgetting the key commands that I have for expose and dashboard. I will notice randomly that when I press F12, for example, dashboard won't come up anymore and when I go to system preferences, it has forgotten my shortcut keys. Any suggestions of fixing my forgetful computer would be much appreciated.
Thanks!

I suspect the cause is a corrupted plist file, in this case the one that holds the keyboard shortcuts for Expose, Dashboard, and Spaces. Alas, I don't know what this file's called.

I am running Tiger 10.4.11 and I have the exact same problem. It is frustrating! I change it back in system preferences and then with no rhyme or reason it changes itself back.
