ICD2 and Wisp628 do not control Vdd so they have problems with
this setup.

PICkit 2 and some other programmers like USBprog from Olin will
control Vdd/Vpp so that they have less probelms with this kind of
configuration (Eg: internal MCLR and internal RC).

This is one of the reasons why I say PICkit 2 is a better programmer
than ICD2. PICkit 2 is also much cheaper than ICD2. It is also
cheaper than most of the proper ICD2 clone.
