Hmm. What hardware/RAM/OS version are you running? I've been using
Vuescan on Mac OS since about 1999 and version 2 or three. The
current v8.2.36 (released today for Windows, Mac OS X and Linux) is a
vastly improved application. You might give it a try ... it's a
2Mbyte download evaluation copy, reasonable even for dialup with a
little patience.

Great info ... thanks!
I've tried Vuescan a couple of times, but it always crashes my
computer to
hang up or Photoshop to crash. It's happened with two or three
versions
of the program. I'd really like to try it.

Hot pixels become more visible as exposure times lengthen: I have a
few on my DS that surface with exposure times approaching 2 seconds.
There are three solutions to hot pixels: Noise Reduction in the
camera, hot pixel removal in the RAW converter, and cloning in post-
conversion image processing. All three work very well ... cloning is
a manual process and can be time consuming, however.
Vuescan's raw conversion does not do hot pixel removal, where
Photoshop + Camera Raw does. You can see the differences in the no-
NR/
NR comparison photo I posted a few weeks ago:

Left-most is NR off and processed with Vuescan: it's the only one the
hot pixels are visible in.
