Forgive me if I missed it in a prior posting, but may I assume you are
running GSPort under the Windows OS?
If you are, use McFadden's CiderPress to transfer the .bxy to your image
and unshrink it there. (Although you could handle that differently).
If you are not running GSPort under Windows, know that David Schmidt's
GSPort Uthernet emulation only works when running under Windows, unless
something has changed about which I'm unaware.
