When I type on my PB, I frequently encounter a problem that I thought was just me: As I type, I will look up at the screen and see that I am suddenly now typing in the middle of what I have previously typed, as if I inadvertently moved the cursor and inserted it in the body of the copy I am writing. This only happens when I am using my PB. Initially, I figured that I must be accidentally hitting the trackpad while typing, even though I take extra care not to. I checked my preferences, and have the trackpad set to ignore accidental trackpad input while typing, but this does not appear to be working. Today, I was talking with a co-worker who recently bought a PB, and I asked him if I could type a bit on his keypad. When he asked me why and I started to explain, he started nodding, and asserted that he had the same problem. I have the rev C 1.33 15" (no backlight), and he has the rev C 1.5 15" w/backlit keys. Neither being trained typists, we are both using the hunt-and-peck method. A: Is there some setting we are both overlooking? B: Are we both mysteriously doing the exact same thing when typing, despite our efforts to avoid contact with the trackpad? C: Is this a common problem with PB's (or laptops in general)? D: Is there something wrong with both these Powerbooks?
