Screen Calibration Confirmation

I've found it can be difficult to point with one hand and move the cursor and click with the other. Being right handed I found myself pointing with my left hand so I could use my right hand so select and click the calibration boxes. This lead to less than stelar screen tracking as I calibrated with my left hand but was using my right. I switched things around a little bit so you can now click or simply press the spacebar to confirm your calibration point and it makes the calibration much easier.
