Hi Bruce

My programme is exactly the same as yours (I removed the 1 from OSCCON bit 0). It is just the same as before. I have a 1 Mhz square wave on pin 4 and a sawtooth waveform on pin 5. I have removed everything else in the programme now apart from a LED flashing on RA1. If I try to do that on RA4/RA5 - zilch. The relevant config line was commented out in the PBP pic inc file but I had also tried programming both ways with no luck.
