I'm running Nexiuz 2.2.4 on Mac OS 10.5.4 and recently purchase a Logitech Dual Action controller to hopefully improve my game. The OS sees the controller in the hardware profiler but the controller doesn't work in the game. Is settings or configuration needs to be done to use the controller?

Thanks in advance for your help!

Click on 'Settings' dialog in menu. There is a 'Use joystick input' check box there that you need to click on.
