how is this "servo thread" created? Is it an OpenSG thread or is it
created by another library? In the latter case you need to tell OpenSG
about that "foreign" thread, by calling something like this from it:
OSG::ExternalThread *tr;
tr = OSG::ExternalThread::get(NULL);
tr->initialize (0); // 0 == OpenSG Aspect you want to use
Hope it helps,
Carsten
