    Just curious...which bit fixed the problem?
    Invariably, it's usually that one little bit that fixes everything...

    those 6 lines allowed me to use an accurate inside clock and to use all pins as digital input or outputs:

    DEFINE OSC 4
    INTRC_OSC_NOCLKOUT
    INTRC_IO
    OSCCON=%01101000
    ANSEL=%00000000 'this comand disable all adc
    CMCON=%00000111 'this bit disable all comparators


    the two last commands fixed the problem to get just digital inpout and outpout on all 15 pins available, and disabled all adc and comparators.
