[luau] annoying touch pad

[R. Scott Belford]

Some time ago I put Mandrake on my ibook.  It has been a great relationship 
save for one annoying issue: my touch pad.  I am clumsy and my touchpad is 
huge.  I cannot do anything without accidently hitting the touch pad and 
sending the cursor to wherever the mouse happens to be.  Anyhow, I have a 
question:

Do you know how to disable the clicking feature of my touch pad?  I obviously 
can't disable it because I need to use the mouse, but I don't want my light 
touches on the pad to be taken as mouse clicks.
