With the DEBUG option in FME Desktop on, the log file will contain a number of additional information lines.
That can be very helpful in solving issues.
But it will also contain some additional errors that can cause customers to panic.
I spend almost a day explaining to a customer (who had the debug option on) that this could be ignored if the workspace does not fail:
BADNEWS: File D:FMEDesktopmetafileMULTI_WRITER.fmf could not be opened (tabrdr.cpp:161)
It would be great if the messaging could be cleaned up, so unneeded messages do not appear.
