    Between the i/o and VCC?


    EDIT:::: MIIP they have to be connected on PORTB, between i/o and VCC.

    EDIT2:::: You could also try to use those internal...
    Code:
    OPTION_REG.7=

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Oups...
    Add
    Code:
    OPTION_REG.7=0
    At the top of your code, this should enable the internal Weak-pull-up on PORTB. Make sure you place this code line at least under the TRISB=xxxxxxxx line.. if there's any
