The 'Dalmellington Bug' was particularly interesting: - While transferring £8000 from the main branch to a sub-branch, the system screen froze, the user pressed enter three more times, and each time they user pressed enter the system repeated the £8000 transfer, ending up with £32000 transferred, while the screen remained frozen, hiding what had occurred from the user. - The investigation showed that there were 112 potential occurrences of this bug over 5 years before it was fixed.
