Untested, uh? Your sphere is a little on the way of sight :-)
I would made it:

sphere { <0, 0, 3>, 1 pigment { color rgb 1 } finish { reflection 0.8
diffuse 0.1 } }
plane { y, -1 pigment { checker color rgb 1 color rgb 0 } }
light_source { 10, color rgb 1 }

(I like to space my code :-)

OK, I render it as 1280x1024 AA 0.3 PNG output, stop it in the middle
(Alt+G). I add +C, restart: preview display quickly the done job and
calculate the remainder. Again, OK. The intermediate PNG images are even
displayed OK by IrfanView.
So, no problem for me on WinNT4.

Mmm, however, I got two rendered files (seemingly identical) and a message
indicating it wasn't able to open the original file, so it was creating a
new one.
This can be related to WinNT file access problem I have sometime (ie. a file
is locked even after the end of the locking program).

Regards.
