I occurred to my why the ICD2 probably has this problem.  Unlike a real high
voltage programmer, the ICD2 normally operates with the target supplying its
own Vdd.  Some PICs required specific timing or sequencing between Vdd and
Vpp, which can't be done without controlling the Vdd line.

Maybe the ICD2 overcomes this if you set it up to supply target power, but
I've never tried this.  Otherwise you have to use a real in-circuit
programmer unless the target chip is removable.
