Default Navigation button unlocking screen

Hello,

I'm currently using http://forum.xda-developers.com/show....php?t=1426339

AN-Droid 2.0.0. It is a great rom, but I have one problem. If i press navigation

button once the screen turns on and another press unlocks it (the defult power

button unlocks it as well). How can I reset this feature, so only power button will

unlock the screen?

Thank you
