Yes, that's a possibility too.  One child I test with insists on an
external mouse, even if I'm offering them an XO-1.5 - which has an
entirely different touchpad model that has never shown the symptom.

I don't see enough data that newer builds make it worse, but data would
be useful.  I'd like this to be evidence based.  How would you capture
the data reliably?

Ah, you're beyond my knowledge at this point.

I don't know of any way that involves only the laptop or software.

Quantifying use and behaviour would require a video camera on both the
touchpad and the screen.  Or accurate reporting from both people who
experience a problem and those who do not.  Self selected reporting from
community enthusiasts isn't as reliable.
