Octopus doesnt get any support anymore. Maybe you can use the information I found at : http://www.theeldergeek.com/forum/lo...hp?t10400.html

It's about how to make a script that calls the api to switch the buttons.

start -> run -> CMD

Code:
 
RUNDLL32 USER32.DLL,SwapMouseButton
Running it again doesn't reverse to the "right handed mode", though
