RUN file format bad or incompatible

2011 August, A-Shell 5.1.1228: Improved handling of "RUN file format bad or incompatible" error: the first time this error occurs, the module is re-loaded from disk. If it happens again, then the error is reported. This helps eliminate rare situations where an updated SBX gets loaded before it is full written to disk, or where some other mishap has caused the copy of a program in memory to become corrupted even though the one on disk is good. Such events are always logged though.
