moving on its own is one kind of naughty disobedience ,now it's just non responsive, i still can move it, but it needs much much more extra effort, i think it has something to do with the palm check/sensitivity setting i did yesterday.
Did you do trial and error on the TouchPad settings ?
Did you put your settings at the same position as mine in the screenshots ?
My settings are still quite sensitive but I am so used to it now I rarely make a mistake.
If you find my settings to be too sensitive (cursor moves erratically) then move the Sensitivity slider to the right one more notch.
I would not recommend moving PalmCkeck any more to the right.
Having the Touchpad setting too sensitive can make it look like a faulty Touchpad because the finger motion has to be absolutely precise. eg:
I have enabled Tap = Left Click and when my touchpad was too sensitive i had to Tap exactly straight down. If I did a Tap on even a slight angle then the cursor would go sailing off to the left or top of screen because the touchpad recognised the 'push' to the left or top of the touchpad
