I have now looked at the code and it seems to be a pure log error. In your dumps above you see that the values are 42 04 7F FF FF FF and 42 05 00 80 00 00 00 and those two are correct. > I am not sure how this could be fixed.

Changing %ld to %lu should do the trick. /MF ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
