Random automatic clikcs on a MacBook Pro

[J. Pablo Fernández]

Hello,
I am getting random automatic clicks on my MacBook Pro (running Kubuntu, of 
course). That is, I am using the computer, I don't even have my hands on the 
touchpad and a click happens... sometimes it is disturbing (changing on focus 
or pasting something... seems middle click happens as well... haven't seen 
right click yet) but it can be disastrous.
Any ideas what to do? I think I am using Synaptic touchpad drivers, but the 
appletouch module is loaded.
Thank you.
