Reading Synaptics > product description it sounds like entire surface should be clickable. In the case of ClickZone, the click in the button area is taken as clicks, if I understand correctly. The problem is, however, not about where to click. It's about the precision. When you click a pad, your finger slips a little bit in millimeter. This already corresponds to a few pixels, and the pointer moves away from the point you wanted to click. In my original patch, I disabled the pointer movement in the button area before click for avoiding this problem. Takashi
