That's wy, on my page, I asked non-US citizen to not download the code from the US-located provider I use and to request the routines by email (I do not live in the U.S.A. so I am not exporting anything from there). > > > > > Marco, did you ever get the bugs out of your implementation? > > > > Andy (#5) I just answerd at this qustion in another message.
