I'm sorry for posting accidentally in German, I get around so many forums the languages simply get mixed up sometimes. It's right that I got the information from reanimatolog, he is quite busy at the moment so he had to put the work on bcdw down for a bit, but I hope he'll be back soon, he usually is.
