BoostC debugging with PICkit 2 and MPLAB

Anybody have this nailed? Sometimes it works fine, but other times (like today's little project) I just can't get it to work properly at all. Very frustrating, as I'm stuck until I find out what a couple variables are doing (something very wrong and strange, I'm sure ).

Run to cursor and breakpoints don't work. It halts (usually), but not where I tell it to. Usually quite a few lines before.

I'm using the one-wire lib functions to read an 18B20.

Hmm... Switched to my Inchworm+/Unicorn (USB ICD2) and it works as advertised.

EDIT: I see that in MPLAB V8.14, PICkit 2 programming/debug support for 18F248 is beta only. I'm running V8.02.

Results from the 18B20 are still out to lunch, but at least I can see what my variables are doing now.
