    Try setting WPUA register to $3B and see if it makes any difference. Weak pullup may be enabled on RA2.

    WOW! Problem solved, and you did it first try. I'm humbled, and very appreciative! Who would have thought a weak pullup would kill the oscillator? I would have never found this.

    Thank you so much for the assist, and for saving what little is left of my hair.
