I'm not sure I'm familiar with HackCS either. I haven't re-tested that class lately, but because of this bug I installed PEMEditor only for Edit Property/Method option, so now it's a bit inconvenient for me to add new property/method. I think I'll switch for both - I hope I would not need to mess with this class again.
