    Hi Brent!

    Acctualy I have one programmer and it was not working properly (PROPIC
2), to my surprise RB4 was connected to +5V also, I just hardwired the pin
to GND and programmer is now working great. Thank you a lot for the tip, by
the way PROPIC2 is much faster than ICprog which I have tested, let me now
if uou want a copy.
