A significant number of the original Stylus Zooms (35-70mm, black body)
develop light leaks around the back cover.  The solution is to adhere a
strip of self-adhesive felt along the top edge of the back frame (above
where the back door closes) and a strip of foam along the bottom edge of the
back door outside the rubber seal.  Corrects the problem 99.9+0f the time.

Actually, from my experience, it's alot easier to wait for a sunny day to
check for light leaks.  I've fired a flash 100+ times from every angle at a
camera with film in it to check for a light leak only to have it come back
after only a few minutes in the sun.  Things can happen as you twirl the
camera in sunlight with light constantly strking it that don't happen when a
flash fires 1/10k second....
