Thanks a ton Kevin, although when I view your PDF (on either Unix or
Windows), I'm seeing the same (poor) image quality I'm getting.  If
you compare


with either of the images on page 5 of your PDF at


you'll see that the PDF version is different than my PNG.  It's got
extra pixels, the text is kind of goofy, and it just looks "funny"
compared to the original PNG screenshot.  It's like it's been shrunk
or stretched, but without being resampled so it's just lost or gained
pixels randomly.

Anyway, your PDF has exactly the same problem as what I've been getting.

What tools are you using?

Does anybody know if Ghostscript is involved with this process at all?
I'm running GNU Ghostscript 5.10, and noticed that there's a 5.50
version out...

Thanks for everybody's help and patience.
