I just got my c140-XL today, and so far am very impressed. However, I'm trying to configure the fingerprint reader, and I'm getting an error. It's telling me I need to run the calibration tool before I can do anything. Unfortunatly this tool does not seem to be in an obvious location, nor does any of the documentation I have talk about calibrating the fingerprint reader. Does anyone know where this thing is located? Edit: I guess a good question would be: did you need to do something to get thereader to work, or did it work right out of the box?
