Mac Forum / General / Portable Macs / January 2006crazy trackpad or keyboard?
I have a 12" powerbook with a consistent problem...as I type, the cursor intermittently jumps to another spot on the screen and of course my text gets all garbled. Sometimes (like in Mail) the program opens a new message window and the second half of my text is in a new message (until I look up and notice the error). Anyone else experience this...any software fix or is this back to Apple for repairs?

But the extra window in Mail is something else... > I have a 12" powerbook with a consistent problem...as I type, the > cursor intermittently jumps to another spot on the screen and of course > my text gets all garbled. You're positive you're not brushing the trackpad with your arm or thumb by accident? You might try going to System Preferences -> Keyboard and Mouse -> Trackpad -> and check "Ignore Accidental Trackpad Input." See if that helps. You might also want to reset the Power Manager circuit, which also controls the trackpad. To do that: 1. If the computer is on, turn it off. 2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes. 3. Wait 5 seconds. 4. Press the Power button to restart the computer. (Copied from http://docs.info.apple.com/article.html?artnum=14449 which explains more of what the PMU does.) If neither of those helps, yeah, I'd take it back and see what they can do for you. Good luck.  SignatureGarner R.

It might also be worth turning off "trackpad gestures". Some people find them useful, but if you're accidentally triggering them, you'll probably be better off without.
