Good to hear that you're getting on in the right direction.

In case anyone were alarmed by my statement about it possibly beeing PBP causing the problem, don't worry. I took a look at Melabs site and found 16F87/88 includefiles for PBP2.43/44. Thank you Melabs :-) . I checked the asm code produced by ADCIN and it looks just fine. It fiddles with the correct bits in the correct positions.
