Hi Dieter,
Unfortunately the info below doesn't really give me much more of an
ideal of where the problems has stemmed from. Could you try a debug
build and see if you can catch the location of the problem.
As a general note about particle effects which are being transformed,
what you will need to do place the particle system itself at the root
of your scene graph, rather nested in the scene graph, as you should
be emitting particles into the air rather than local to the particle
source. The osgparticleeffects example provides an example of this.
