[Doggiebox] 70s ludwig kit and key assignment.

Hello, this is my first entry to the list, hope I'm doing it correctly. I have a couple of questions. First one, why can't I assign key shortcuts to the Ludwig kit? I was trying to do that right now, and all went well until i tried to save it. A message box pops down that says "Couldn't save document." So I can't assign keys in that kit? haven't tried doing it with any other kit yet. Second, Is it possible to get hold of the icons of the ns_kit? If i am to make my own version, it would be a lot easier if I had the icons. Thanks! Håkon Pettersen, Norway
