problem with 16F84A for 5x7 LED matrix

hi.
Please help me. I just built a LED matix circuit(attatched schematic below) with 16f84A and CD4022 counter. I tested some example hex files for movnig sign and I am not satisfied with the output because of an automatic reset which is unwanted. I dont know how to remove this....
What exact happen is that if the code of output is "HELLO" by assembly it shows H and E, not others, then starts again from the top automatically. It takes time about 3 seconds.

I tested other examples and found the same problem the 3 second-automatic reset.
I guess the MCLR or CLK problems, isn`t it? Or code...


As you can see the circuit, I used RC oscillator(4MHz) instead of crystal, the source from http://talkingelectronics.com/projects/5x7Display/Display_03_Construction-Part1.html I made a simpler circuit.

Thank you,

My guess is that you need to disable the watchdog timer in configuration bit settings.

Your coding style is terrible. Please do not write any more code until you have gone through the Gooligum tutorials here:
