Whenever I tap my trackpad, it pastes any text I've recently entered. I'd like to continue using the trackpad, but suppress the nasty pasting behavior. Any ideas on how to do that?

Am running CentOS 4.3

/etc/X11/xorg.conf contains ...

Section "InputDevice"
Identifier "Synaptics"
Driver "synaptics"
Option "Device" "/dev/input/mice"trackpad
Option "Protocol" "auto-dev"
Option "Emulate3Buttons" "yes"
EndSection
