Help with Camera Zoom FX

[d12bn]

I have a Sprint HTC Hero and just loaded CZ FX. Can someone tell me how the manual focus and auto works? I know how to turn it on and off just don't know what its doing. With the stock camera when you touch the screen it focuses on that spot, with FX I can't figure it out.

Also with FX when I touch the screen it takes a photo even when that option is turned off?

Thanks
