I would like to add that this seems to be very much a finger detection
issue.  I'm having this problem on an Asus G73SW recently upgraded from
Natty to Oneiric.  I booted the Oneiric LiveCD to see if it was a config
issue, and I still have problems, although they're a little different
(the three-finger window drag doesn't seem to work from the LiveCD, the
window handles don't appear from three-finger clicking either).

My cursor locks up with varying frequency, but everything else is still
in full swing.  I can click with the physical buttons, an external mouse
works perfectly, and the keyboard is still responsive.  However I
experience an additional symptom that I don't see anyone else
describing.  After locking up briefly, sometimes it will move
erratically on its own.  It'll grab a window, jerk it all over the
screen, and sometimes leave it positioned halfway off-screen or maximize
it (by dragging to top, I believe).  I get the impression it thinks
there are fingers all over the touchpad, almost like it thinks I'm
palming it, but a little different.  It seems to think there are several
points of contact either stuck or moving erratically.

I have no problems with this touchpad in Windows 7, nor did I in Natty,
so there's no question we have a bug in an update.
