I have a problem with a large scene because with full scale of space navigator for translation my scene didn't move.This 's not occur in a simple small scene. I wish a new driver should have a multiply scale for each axis
try this
create a cube at 50,000 unit and set 3d connexion panel like this
VIEW-Move Scene
Rotation Pivot-Scene/Object
fly mode-on
disable rolling-on
Sensitivity-Translation Max Value,Rotation Mid Value
Set max translation value in global 3d connexion control panel
a rotation not a problem but in translation 's slowly than 'S' Key+mouse drag much more
