I'm on the hunt. Again.
You see, there is a dust mote in my camera's eye that simply must be erradicated. Get out the cleaning tools. Bring in the bright lights, the better to see with. Work in a dust free cleanroom (or at least, not in the wood shop).
And remember: as when blowing out birthday candles, keep your spit to yourself...
