Hi!!

I have a PIC16F877 circuit and im having big problems to get it stable.

Problem:
It will only run for a short time and only if im touching GND with one =
hand.
When I touch GND with one hand all I have to do is wave the other hand a =
few inces from the circuit to get it to reset, now if I keep that hand =
really still I can watch it run for like 5-10 secs before it lock ups =
(not resets).

Hardware:
All I have is a 4Mhz 16f877, osc caps are 27p
One LED on RC4 with a resistor to GND.
Max232 with all the caps on RC6 and 7. The other end of the max232 is =
connected to my com1.
A reset button with a 10k pullup resistor.
All my cables are short and nicely layedout and my powersupply delivers =
a stable +5v.

What I have tried so far:
I have tried to put +5 on either and both of the VDD pins, same thing =
with the VSS.
I have put caps between none, either or both of the VSS/VDD pins.
I disconnected the Max232 on rc6 and rc7, still the same problem.
I tried a 16f874 at both 20 and 4Mhz, same thing.

Help me!
/Fredrik
