the old keypad behavior gets too sensitive

[Tiago Marques]

I still have this same issue with my 1.5 B2, which I reported to the list a
while back. The pointer moves without touching the surface, although the
distance is more like 2mm than half an inch for me. It's still annoying most
of the time but one can live with it.
