Button question

[ElAguila]

I have the mogul working and I have not customized a rom yet so I have the latest sprint rom. There is a button under the wheel on the left side of the phone. That button says ok with a circle around it. When I am scrolling with the wheel and then I click the okay button that is under the wheel on the side, instead of selecting the highlighted item, it brings up the start menu. Is there any way to map that button back to normal function of the ok button?
