Keyset fire button assignment

[AZRetroGamer]

Hi,
I'm trying to run Pharaoh's Curse.
I have a Microsoft Natural Keyboard Pro on a Dell Inspiron 9100 laptop running Windows XP SP2 with CCS64 v3.0 Beta 1.5

I went into the config of the program and assigned Control Port 1 to be KeySet #3.

This should make the Right Control button on the keyboard the "Fire" button. But it doesn't, it makes it pause/unpause the game.

So I tried other keys.

No matter what key I assign "Fire" to, it only pauses/unpauses the game.

Any ideas ? I only have USB (no PS/2 Connectors on this laptop).

Thanks !
