NextWindow Plugin Touch Filtering Issue

I have a NextWindow Touchframe and some issues with the detection of movement inside the frame.
It is quite big (140 x 140cm) and quite precise. The only problem is that movements of less than 20 mm are not registered. After talking to the manufacturer he suggested that there could be some filtering within the vvvv plugin.
@vux: could that be the case?

from a quick glance at the source i’d say there’s no such thing going on in the node.
how is windows mouse cursor movement through native touch input coping?
