I've had this happen, is the alignment icon (the cross on the screen) moving after you touch it? If it is, make sure you set it with the stylus, not your fingernail, and what usually works for me is to kind of brace my hand with my pinky while I press on the crosshair, aiming for the middle as best you can. Screen protectors can also sometimes mess up its alignment, normally it takes one shot and I'm done, with the protector on it sometimes takes up to 3. Odd thing, my qwest apache never cared if it had a protector on the screen, only my sprint seems to.
