I had the same problem after upgrading to 9.10 alpha.
The fix was to :/usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi
sudo cp /usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi /etc/hal/fdi/policy/
Reboot
Go under System -> Preferences -> Mouse
Go under the "Touchpad" tab Select (check off) the "Enable mouse clicks with touchpad" box
(While you are there, you may wish to disable it while typing =) )
