I have a user that is on his third 8800 and it is driving him crazy! When trying to type an email, if he presses the trackball it will type "ou". If he presses the ESC button, it types "lh". I have taken the trackball out and aired it, but still does this. Plus, I updated the software (OS and Handheld), no avail. Any ideas???
Sounds like he's getting it wet somehow. Sweat from a pocket or holding it to his face when talking on the phone, rain, bathroom shaving....but it sounds like it's getting moisture in the trackball/keyboard.
Just because the moisture indicator is white doesn't mean the keypad isn't getting some kind of moisture. My money is on moisture. If he were to remove the battery and let it sit for a few days I'm guessing it would fix itself.
