Comment 32 for bug 386017

> ... touchpad side-scrolling that easily triggers right-click [...] can't be considered anything other than a bug
Note that it does not behave like that on all hardware - on my Latitude 2100, I can scroll with no problems and the tap triggers only if I really tap on the corner.

> even when tap-to-click is completely turned off in the Touchpad settings
Of course, you are right, this is a bug.

I am quite sure the patch won't go into Karmic, but I think it would make sense for Lucid (and therefore maybe into Karmic proposed or backports?).
