In cases where the system knows it's bad but not why it usually means that the designer of the software didn't envisage that specific event happening. The problem with systems of this type is when that happens the safest thing to do is to stop everything so the global exception event will normally do that.
Again, thank you! But "if the system knows it's bad" you are halfway there...
