My wife's trackpad on her one year+ old iBook has a clicking sound come on when the trackpad it touched.  Not every time and I have already made sure all menu sound effects, etc. are turned off.  It is  a sound I have never heard either.  It is NOT coming from the speaker but the trackpad/keyboard area.  Has anyone else had this problem?  A short maybe?
Thanks!
