PP problem versions 2.9.5 and 2.9.6

I installed both versions 2.9.5 and 2.9.6 and both have the same problem with the parallel port. I have an MPG configured with a C10 and in version 2.9.4 it works perfectly, but in either of these last two versions it doesn't. When running LCN you can see with the hal that the parallel port is indeed loaded on the pins, but none of the functions programmed in the MPG work. I went back to 2.9.4 and the MPG works again.
