Comment 3 for bug 247433

I can also confirm the bug with the following configuration in xorg.conf:

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"

 Option "VertTwoFingerScroll" "1"
 Option "TapButton1" "1"
 Option "TapButton2" "3"
EndSection

But I have tested the patch you sent, and it has not fixed the problem for me.
As you said, by quickly two-finger scrolling, the right-click menu indeed appers.
I might look into a solution, but since I am going into a 30-day vacation right now,
it may take some time.

Just an observation: this BUG has nothing to do with my mactel patch,
since it deals with multifinger tap-clicking, and not with the multifinger
button-click.

This is a VALID BUG that affects EVERYBODY using the original synaptics
driver with the configuration tap-click + two-finger scroll, and it would
be a LOT BETTER if you could submit this bug upstream instead.
