I have had the same problem because I keep my PRG files in a Programs subfolder while the compiled APP is in the parent folder. Even though my PROGRAMS folder is in the VFP search path, I could not avoid the Source not available until I copied the source code to the same folder as the APP. This is a real PITA because the next time I issue a MODI COMM, I am editing the copy in the parent folder while the PRG in the Project Manager still points to the one in my PROGRAMS folder.

To overcome this problem of Source not Available, I had to modify my Project class to delete these copies from the parent folder before building the APP or EXE. Then in the after build, I have copies of the PRG copied back to the parent folder.

Now I just have to remember to only edit the PRGs via the PM or delete the copies first.
