Jonathan,
I agree with Gordon. Put in a 0.1 uFd disc ceramic cap ( from any Radio
Shack or equiv. ) and you'll be fine. In the unlikely event you can't find
one let me know offline and I'll mail you one.
Best regards, Steven

Probably another little disc ceramic. It looks like one end goes to
ground, so it's either some sort of decoupling or for very crude
debouncing. Draw out the circuit around that bit of the board, and see
where it goes. My first guess would be another one the same as C14.
I bet it's not hugely critical.
