Looks like you have it worked out...

Just for the information:

"""""""""""""Running Windows 7 Pro 64bit.
Here is the 3dconnexion driver info:
Release Version: 3.16.3
(Driver Version: 6.16.1)
Firmware Version: 4.31"""""""""

I have the same OS and release version, but, My firmware is 4.04, which has my driver version as 6.16.0...

Later.
