  Using up-to-date karmic as of 15.08.2009
  
  Problem:
- When using the "virtual scroll" on the touchpad (i.e. only moving the finger on the right side of the pad, not pressing any button!), occasionally (apparently randomly) incorrect events are generated.
+ When using the "virtual scroll" on the touchpad (i.e. only moving the finger on the right side of the pad, not pressing any button!), occasionally (apparently randomly) incorrect events are generated. It also occurs with tap-to-click disabled.
  I can easily reproduce the issue by placing to fingers on the right side of the tab, i.e.
       _____________
       |       finger ->|
       |                     |
       |       finger ->|
       |____________|
  
  and tapping and slightly dragging with both fingers at a fast rate.
  Looking at the output from xev while doing this, between the events 4
  and 5, occasionally some events of type 2 (center click) and 3
  (rightclick) appear.
  
  This also happens when using the touchpad "normally", i.e. browsing in
  firefox: quite often when scrolling through pages actions get perfomed
  that are either triggered by the center click or by a funciton of the
  contextmenu (which apparently hides again so quickly that one does not
  see it). To be noted is that this issue is NOT specific to any progam.
  
  I started noticing the problem since the last xserver-xorg-input-
  synaptics update, possibly related to the issues created with the patch
  that was introduced there, such as bug #405943.
  
  Hardware is a lenovo T400.
