PICkit 2 and RBC interrupts

This is probably unique to my situation, but I thought I would share anyway:

I am trying to program AND operate my 16F946 from the PICkit 2, using ICSP. It programs fine, but the RBC interrupts would not work. I am using RB6 and RB7, which happen to be the ICSP data and clock lines. My hardware uses pullups to VDD on these pins, with switches to ground, and the PICkit 2 has PULLDOWNS on these pins, even when it's not programming. In order for it to work, I have to disconnect these lines from my board.

The MELabs U2 does not suffer from this problem
