ok, the problem is : the gluCallbacks were defined without
OSG_APIENTRY, which resulted in corrupted memory. I commited the fix (so
it should be available soon). If it is urgent and you have a self
compiled version go to OSGGeoFunctions.cpp and add OSG_APIENTRY to
all gluCallbacks (they are just in from of createConvexPrimitives).
The first one should look like this :
void OSG_APIENTRY gluTessEdgeFlagCB(GLboolean /*flag*/)
{
.
.
}
the others follow.

gerrit
PS: I have no clue why it works on XP but not on 2000 and why it did not
hit us earlier ;-)
