Seems I may have stumped everyone?

The plot thickens. Last night, out of the blue, it started working properly. I had made no changes to the program. Just as suddenly it returned to producing the wrong sound.

I swap the buzzer and it works properly so I think that the problem has been a bad buzzer, but when I used the "bad" one again with the other program it still works fine 100% of the time.

So the new program requires a different buzzer then the old program to make the same sound. I don't think so.

Anyone have any ideas at all keeping in mind it is the SAME PIC I'm using each time with the same components, just swapping out the programs which are within 66 words of being the same length of each other with the same sound values.
