On previous versions when you had to define "Computer 1 is left of Computer 2" and so on, this would have been easy, but with the new configuration, I can't figure out how to put the same computer in the diagram twice. Essentially with the older versions you would set your computer monitors as:
Dual-Right | Single | Dual-Left
Then you would make your config as follows:
"Dual is left of Single"
"Dual is right of Single"
"Single is left of Dual"
"Single is right of Dual"
This creates the ability to loop completely around.
Edit: I got it. You have to save the configuration then edit it.
1. Put your two computers in the picture diagram via "Configure interactively"
2. Back at the main screen, select File > Save Configuration As
3. Name it anything you want and save as .sgc file
4. Open the file in notepad to edit
5. Find the Section: links and edit as follows:
section: links
Single:
right = Dual
left = Dual
Dual:
right = Single
left = Single
end
6. Save and close
7. Back in Synergy choose "Use existing configuration" and point it to your .sgc file
