I just upgraded to this, and I see Draftsight now supports 3d mice, which is nice. 

Then I ran into a slight problem.  I was setting up my 3d mouse (SpaceExplorer).  When I change the Zoom Direction to Vertical (so the model zooms in when I pull up vertically on the puck), the Up/down directions are reversed.  Left/right is fine, and the zoom direction is fine, but up/down is reversed.  I tried to reverse that axis on my 3Dconnexion panel, but that didn't change anything.  I cannot figure out a way to get this axis reversed.

Another side note, the model behaves as if "Dominant" is checked, which it is not.  Minor annoyance, it just makes for choppy movements.

Anyone else run into this?
