Hello,

OK, it is working now.

In the pix_openni/README, i would prefer to follow these instructions in 
5 steps (in the middle of the page) :
http://groups.google.com/group/openni-dev/browse_thread/thread/49a4dd13c045c1a2
instead of :
*    get and install OpenNI, NITE and the hacked Primesense Kinect driver
     --> instruction: https://github.com/avin2/SensorKinect
     http://www.openni.org/Downloads/OpenNIModules.aspx

And all should be OK.

Matthias, the hand tracking should work fine ?
Thanx for this external.
++

Jack
