Ok, I'll keep the ipp14 with utmost care ;-) Changing the IPP protocol in a way, that it becomes incompatible with the previous versions I find strange. While searching the net for a solution, I found a lot of screaming of Apple users that had exactly the same problem. I understood, that Apple quickly provided a fix and the problem was solved. So it could be a bug rather than a protocol modification. Anyway lots of thanks for your quick and effective help. Adrian.
