Hi @ alll, in my multitouch table IR Laser I have this problem:
When I touch with two finger simultaneously, the S.O. recognize a single finger dragging quickly from one point (of the firts finger) to the second point finger.
The effect is as the cideo below:

I’m using CCV 1.5, with BSQ Simulator as TUIO client and Microsoft Surface SDK. I’ve tried also with multitouch vista as TUIO client but the problem still remains…

Studying in deep the problem, seems that CCV keep the wrong id for two distinct points!
This is my TUIO log:

CCV instead generating ID 530 sends multiple packet with id 529 ( xpos: 0,3313466 and xpos: 0,9809802).
What can be wrong in my CCV 1.5 settings?
Graphically the blobs are clear and separeted!
