Interesting! But my report was based on my development machine, a PowerBook G4.
Apparently the special instructions are not used or not causing a problem because it also runs fine on the NAS. ----- Please excuse the shortness of this mail which was sent from my mobile phone. If necessary, I will send more information later.
