- Make sure you're using just one or two fingers. Using more than two fingers could cause erratic behavior.
- Make sure you have installed the latest version of the system software. For Mac OS X 10.3, this is Mac OS X 10.3.9.
- Reset the trackpad by placing your entire palm directly onto the whole trackpad for 3 to 4 seconds, and then remove your hand from the trackpad in one smooth motion.
In most cases, trackpad operation will return to normal. If you have updated your system software and reset the trackpad and operation is still not working as expected, test the computer for five to ten minutes. If, after that length of time, there is still no improvement, you may need to contact Apple using the support phone number that is listed for your country.
