Hi mhackney, newer versions of the Mac 3Dconnexion driver stopped working with MoI and I'm don't know why. I posted a question about it on their developer forum and they never responded.

Currently the only way I know to get it to run is to use an older driver as mentioned here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7986.1

but also that may be problematic with new OS releases. This may not get solved until MoI v4 is released, for v4 I've been undergoing a major rewrite, one of the goals of which is to have a native compiled Mac version rather than using the "Wineskin" mechanism.
