When finger reaches

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Place two fingers on trackpad vertically aligned, i.e. middle finger on top 
of trackpad and index finger below it.
2. Move fingers downwards to initiate scrolling.
3. Keep going until bottom finger reached end of trackpad area.

What is the expected output? What do you see instead?

I expect scrolling to simply cease when I can no longer move my two fingers 
down any further.  Instead, the thing being scrolled jerkily scrolls back up a 
bit before scrolling ceases.

What version of the product are you using? On what operating system?

1.0.6 on Windows 7 Professional, 64-bit.

Please provide any additional information below.

This problem does NOT reproduce if I position my fingers horizontally, i.e. 
middle finger on the right and index finger on the left.  It only happens when 
one of my two fingers reaches the bottom of the trackpad before the other.

This problem also does not occur when scrolling up.  I only see it when 
scrolling downwards and my finger reaches the BOTTOM of the trackpad.

I have a Sony Vaio Z and am using Synaptics Touchpad version 7.4 with Synaptics 
Pointing Device version 14.0.16.
