Microsoft Sidewinder Controller Half-Works?

Hi crew,

I am testing my game with the old Microsoft Sidewinder game-pad, and strangely the button inputs work perfectly, but the d-pad doesn't register at all.

I understand that C2 is optimized for the Xbox controller, and I will pick one up soon and do all future testing with that. But until then, has anyone else experienced this and found a solution?

Thank you.
