No, I was never able to correct the problem. I totally removed PBP from my system and re-did the installation, this time using the installation sources of my friend, who does not experience the problem: But I got the identical failure yet again.

Nobody has been able to shed any light on the issue. Nobody has been able to suggest even a way to capture relevant diagnostic data. The trail seems to have hit a stone wall. I have been forced to abandon PIC Basic, due to this issue. (You are the first person who has ever shown concern about it.) I was really hoping someone would help me figure it out. I do not have enough knowledge of PBP internals to debug this situation.

Frankly, I am quite unhappy with MELabs and the entire user community. It would be different if anybody cared whether the product could be used or not. I am switching to the Swordfish compiler, which is being actively supported by the developer, David John Barker (who also wrote PIC Basic Pro). Swordfish is an advanced complier for Microchip 18XX parts. It has wonderful interrupt support and a truly sophisticated structure. I heartily recommend it.
