>Hello antonio,
by any chance do you have a lot of clrwdts around? clrwdt will reset
the powerup and wakeup bits.  also, are your ports initialized ok?
somd pics clear the ports when the program counter resets to 0.   try
inserting a few lines that show the status bits 3 and 4 on leds at
the very top of your program, and see if they are always 1 and 1.  if
the lights dont come on, your ports are on input.

good luck, this is trickier than it looks.
