Palm Check

To prevent mis-touch, the touch pad ignores big active area motions, like
any movement at the touchpad with your palm, you may set the area size
by clicking Synaptics Pointing Device icon in the system tray in the lower
right corner of the desktop.
You can also change other gesture settings (e.g., enable/disable
ChiralMotion) by clicking the Synaptics Pointing Device icon.
