It does sound like a missing pixel. About a year ago I experienced similar
with my Olympus E10. To test the chip I shot a frame of pure black
(Leicestershire sky! If you use black fabric or anything like that you will
confuse dust with pixels.) and enlarged it big enough to see individual
pixels. To my dismay several pixels were white, ie missing, in the frame.
The camera went back to Olympus, just within guarantee, phew, and they put
something called 'pixel mapping' in it. Seems to have done the trick.
