Flock of Birds

[sleiN13]

I've got a problem with the flock of birds tracker (from ascension) and Vizard. As soon as I link the tracker (sensor = viz.add('flockofbirds.dls')) by means of the link function (linkviz = viz.link(sensor,viz.MainView)) the mainview point jumps to a different location and the whole image rolls over 90 degrees to the left. Also any movement from the HMD is mapped wrongly. For example head movement from left to right produces a Yaw motion and an Yaw motion from the head turns into an Roll. This is roughly the case because it's not exactly an 1 on 1 mapping.

My question is how do you get the flock of birds working correctly with Vizard because the default code from the examples and demo's all have the side-turned result.
