I was wondering if anyone could help me with a calibration issue. my setup consists of a projector and mirror rear projecting onto the acrylic, fairly typical. My camera is shooting more or less straight up from beside the mirror. After I do a config the center of the screen has perfect registration but as i move out to the edges the registration gets less and less accurate. By less accurate I mean the points are in line with the touch and the center point but away from my finger by an increasing amount as i move away from the center.

Has anyone else had this happen? Do i need to capture the screen through the mirror to prevent this? Its bizarre because I have calibrated the screen before with great success
