>>no problems with data. just one of the many reports/andor screens I guess is corrupted. Therefore the rebuild stops with the error maessage. But no indication as to what file is the problem file. I remember, in the old days I had tha problem and I had a fix (I believe I had the builder write a log file) but I don;'t remember what I had done. :(

YES I AM
I am not talking about a bug which gets reported by the builder. It is one of the screens or report files which is CORRUPTED SOMEHOW. It does not get reported because the builder dies.
As I said I had this happen years ago and I added a line to a byuilder programto log every object which got compiled. then I could find the last entry and knew which file was corrupted.

The problem is: I cannot REMEMBER the name of the program I modified to do this logging.
