Motorola Droid X :: Want Slide To Answer Phone Calls

Recently I've noticed that I accidentally answer phone calls without realizing it while the phone is in my pocket.Callers then hear the rustling of my phone rubbing the inside of my pocket.I've read that when the Droid X's screen is off, I should have to slide to answer a phone call.However, even when my screen is off and the slide to unlock and pin number lock are active,I am still presented with two buttons when I get an incoming call.This happens regardless of whether people call my regular phone number or my Google Voice number.I have LauncherPro installed.Am I missing something?I'd like to have the slide to answer feature so I don't unknowingly answer phone calls.
