>build up the project from scratch (after deleting the old one) and so forth. This has helped always, but not this time.
If you are debugging app/exe AND the class in question is a prg-based class AND the relative location source<>pjx differs from source<>App/exe

you can encounter source not found. This happened to me in a setup where all pjx were cluttered away in a subdir. What happens if you put an assert in the source of the unavailable parts ?
