configuring keyboard - digital pad keys don't work

I have Zelda OOT (on project64 1.6) and use a keyboard but can't get any of the up-down-left-right keys on the digital pad in the control configuration to work. I've tried the default settings and assigning the digital pad keys to other buttons, I've also tried N-rage's input plugin V2 but nothing.

I've searched for hours but haven't found anything about this, does somebody know why I can't use the digital pad buttons and how I can get them to work?

thanks.

thanks, that explains it.

it really sucks though that you can't even walk straight forward in that game if you know what I mean, sometimes the character is facing you or facing sideways and you don't see where you are going. How do you people deal with this?

Thanks again, I guess I'll just have to get used to it.
