There is a growing body of evidence that the touchpad problems are
related to weather and I have a personal theory that humidity changes
play a part in that.
Both myself and Andres (dilinger) have run tests where moving an XO
between a closed bathroom where you have run a hot shower and made it
very hot and steamy and an the ambient environment will cause the
touchpad to have problems.
My results were very similar to yours but Andres's results were not so
I'm searching for ways to do controlled humidity experiments. Its
difficult because you have to increase the humidity yet not cross into
the condensing range.
