'[PIC]: 16F877 troubling in startup'

   Hello. I have a problem with the startup on the 16F877.

In the startup the PIC start slowly, and it take a few seconds for begin (2
or 3 seconds). Then, the LED's that I have connected to the PIC they blink a
little, until finally they light up and the PIC works correctly

I using the PIC to decode a IR Sony, to read a ADC pin and to generate an
PWM out (for the mometo)

When I run small programs, or I modify (several modify) the current program,
the problem disappears or he attenuates.

As data I count them that the clock is of 4 MHz, the source is regulated and
very reliable (5V), etc.

The program begins settings the corresponding TRIS. Then turn on the pin
PORTA,1. Then reads two pines of the port B to decode IR Sony, it filters
the data and turn on a LED in the PORTA,1 if the codes are correct. The
program waits a "four digit key" and, if it is correct, when pressing the
key DISPLAY, he gives an exit PWM given by an analogical entrance by the
PORTA,0

The program in MSPAM is in

Sounds like either the MCLR pin is floating, or you have Low Voltage
Programming (this is the default) enabled and RB3 is floating.
