I have been trying to assign the "Window Picker" to the F3/Expose key. It simply won't work. The key works fine in OSX
No other commands work with the key either, but if I assign Fn+F3 it works fine.
All other "F" keys work fine for their different functions. I even have the F4 key set to open System Manager.
When I try to assign a command to the key, 0x80 comes up as the shortcut in the Keyboard Shortcuts program. 0xd4 comes up for the F4 key and that one works fine.

About my setup:
Running Karmic 64-bit on Macbook Pro 5,5 13.3"
Triple booting with OSX, XP and Karmic
I have the "F" keys set so the default functions are brightness, volume, etc. I use the "Fn" modifier to use the F1, F2 etc.

I've done some searching on the net and can't find anything. Has anyone else had this problem?

Thanks in advance for any help.
