> How, exactly?  Give me the step-by-step.

Step by step instructions to build Geomview and SaVi are on:
http://sat-net.com/L.Wood/software/SaVi/building-under-Windows/

launch with 
geomview -run ../savi1.4.9/savi


build Geomview and SaVi on 32-bit and 64-bit Cygwin, and compare. On 32-bit Cygwin, SaVi talks to Geomview, you get a view of the Earth with a ring around it when you launch the two, you can control Geomview with SaVi and its menus as expected. On 64-bit, Geomview launched with SaVi:

geomview -run ../savi1.4.9/savi

gives a blank grey canvas window. Though SaVi may be listed as a module in Geomview's main window, clicking that does nothing. There is no piping communication between the applications. At all.

Geomview is available from http://www.geomview.org/
SaVi is available from http://savi.sourceforge.net/
