[Cuis-dev] Trackpad issue

[Juan Vuletich]

Hi Gastón,

I just checked, and the preference is already false by default. So I 
don't think your cs makes any difference.

Please try the attach and tell if it fixes your problems. Usually we 
translate scroll events (that are reported by the VM as keyboard events) 
into mouse events. What the attach does is, if any trackpad scroll event 
is not translated into a mouse scroll event, then just ignore it (i.e. 
don't feed it as a keyboard event).

Thanks,
