It took me a while to find in the web why the touchscreen of my son's Leapster2 had stopped working So I am posting the solution I found on the LeapFrog site. It works like a charm: Question: Why doesn't my Leapster2 respond to the stylus pen? Answer If your Leapster2 does not respond to the stylus pen, it needs to be calibrated. Calibrating the Leapster2 is easy: 1) Ensure that a cartridge is not inserted 2) Hold down the Hint button while turning the unit on 3) When the LEAPSTER menu screen appears, press the A button 4) Touch each of the crosshairs that appear with the stylus 5) Restart unit http://leapfrog.custhelp.com/cgi-bin/leapfrog.cfg/php/enduser/std_adp.php?p_faqid=1736&p_created=1221582020 Users who viewed this answer have also viewed Leapster is not responding correctly to the stylus pen.
