Learning to love the touchpad
I've been fretting over the Synaptics TouchPad built into my laptop. It's temperamental. The cursor floats merrily across the screen, seemingly of its own volition; I lift my finger and the arrow shoots away like a frightened hummingbird. This afternoon I was acutely tempted to put my fist through the LCD screen.
Anyway, I think I've discovered a way to keep the cursor under control: I cool my fingertip by gently blowing on it. Apparently the touchpad registers the heat -- as well as the heft -- of the controlling fingertip, and if you're on edge -- as I was this afternoon, trying to point and click with the accuracy provided by a mouse -- your skin tends to grow hotter, confusing the touchpad interface.
(I've actually seen the cursor drifting and meandering across the screen when I'm not even touching the computer; I still have no clear explanation for this poltergeist-like phenomenon . . .)
