These guys say that they do have 2 capacitors over ground/positive. Though not "as close as possible to the pic", and not those sizes. Further, we're using an external oscillator. Though the static problem I don't think is our biggest problem. Our real "problem" is that they intermittently go into infinite reset loops when powered on.
