Apple released Bootcamp 2.1 with OS 10.5, which allows you to dual boot to Windows XP/Vista on your Mac. Subsequenet to that release, there was a driver update for the Multitouch trackpad which was suppose to improve souble tapping, etc. However it caused a Blue Screen of Death (BSOD) the moment you double tapped, courtesy of applemtp.sys. Many people sent suggestions to Apple to fix this, but it seemed to be falling on deaf ears.
