G1G1, Joyride 1971. Was visiting a friend. Apparently, he keeps
his house less humid than mine. Noticed that when I waved my hand
in the air some two inches above the touchpad, the cursor (e.g., in
Terminal) would move around uncontrollably, and even jump.
In fact, I had difficulty controlling cursor movement when using a
finger on the touchpad. The cursor would move, but would typically
be only halfway across the screen by the time my finger had reached
the touchpad edge. When I would lift the finger (to reposition it
for a repeat movement), the cursor would jump backward or sideways.
(Also, sometimes when I was touching the pad, the cursor would not
move even when I moved my finger.) Within the top right quadrant of
the screen, it was extremely difficult to accurately position the
cursor. [The four-corner-calibration keypress did not help.]
I ended up licking my finger (to make its skin more moist). That
cut back on the wild jumps the cursor was making, although there was
not always a correlation between the distance my finger moved, and
the distance the cursor moved.
[Back home, the cursor again behaved correctly.]
