[sugar] jumpy cursor problem and sugar issue

[Mikus Grinbergs]

It might not be purely a touchpad issue.  Once in a while I've seen 
the cursor jump to a corner -- this is while I'm using an USB 
trackball, not the XO touchpad.

p.s.  When using the XO touchpad, a sure way to get erratic cursor
      behavior is contacting its surface with two fingers (instead
      of one).
