Sensitive touchpads are great for easy cursor moving and multi-touch gestures, but their sensitivity is a reason of the problem of accidental taps and clicks, especially while typing a text.
Touchpad sensitivity is controlled by a software driver. Some notebook models have a special Control Panel applet to make sensors more or less sensitive. Try to decrease sensitivity of your touch panel, maybe this will solve the problem.
Anyway, there is a solution to automatically block the touchpad to prevent accidental clicks while typing.
Touchpad Blocker software solves problem of too sencetive touchpads by disabling the sensor for a period (less than second) if some key has been pressed. This trick absolutely removes the problem of jumping cursor by accidental taps and clicks.
You can change the delay and a keyboard shortcut to turn touchpad blocking on and off as you wish.
