Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after…

• Adding click/double-click events to static group box controls

  - by omatai

  Having realised my own reasons were way too dubious, I've now gone about this a different way. But I'm still curious... For reasons of nostalgia, familiarity and laziness, I'm coding a UI with MFC.
