Warning for PICkit3 Users

Be very careful not to press the "Programmer-to-Go" button when there is no image on the programmer (either the Olimex PIC-KIT3 or Microchip's own PICkit3). Doing so will put a PIC32 microcontroller into an irrecoverable state. See this Microchip Forum thread for details.
