Simple program - Strange problem!

So Sorry, My Mistake, need a redbull. I will correct my sentence:
" If GP1 is high, and gp0 is activated via gp5, it gets high and goes low after 2 seconds appx.
If GP1 is LOW, activating GP0 via gp5 makes it high but not low"

Can't say what would cause that. Programmed a 12F635 here, and it works just as
expected per the code example above.

LEDs on GPIO.0, 1 and 2, and buttons on GPIO.3, 4 and 5 with pull-down resistors, and
button presses taking inputs high.

Thanks Bruce. It was the PCB track getting short. It's working fine now.
