as with the old touchpad driver, the best thing to do when the
touchpad is behaving badly is to remove your finger from it for a
few seconds.  it will usually detect the condition, and
recalibrate.  the tricky part is that if your finger is still on
or very near the touchpad while the recalibration occurs, the
problem probably won't get better, and may get worse.

it's very frustrating that the laptops have such a crippled input
device.  all we can do in the driver is try and notice when things
"go bad", and make teh best of it, but we can't _prevent_ them
from going bad.

thanks very much for your testing.

when you say "right part of the pad", i assume your finger is still in
the middle section, and not all the way into the right section.  the right
and left sections will definitely not respond.  if your finger is just
at the righthand edge of the middle section, then your touchpad may truly
be faulty.  you can run a diagnostic:  hold the "Check" gamepad key while
booting, and then hit ESC  to get an "ok" prompt.  then type "test /mouse".
