I was seriously thinking of upgrading from PBP 3.0.7.4 to 3.0.8, but with all I have read here maybe not?
I too like Henrik rely heavily on MPLAB for source level debugging and simulation and I can't afford to lose that functionality.

Henrik, have you pinged Charles Leo about these issues?
Hopefully they can put together an install MOP/Manual to get 3.0.8 working for all of us with the correct version of MPLABX with the functions we need working.
