--- Comment #6 from gsaumure79@videotron.ca 2012-06-27 21:02:44 CDT --- My bad, I use Rhino 3D V2.0 because the V4.0 is known to be not working on WINE.
Anyway this bug is not critical because the program run almost flawlessly (It's impossible to manage Layers). It's just annoying to have this error message box when I close the program.
Unfortunately, no user-friendly 3D modeling tool exist on Linux platform. I have try Blender but I can't create a simple sphere in less than 30 minutes.
@DAn Kegel : Is the app downloadable? ---> No it's an install CD with key protection system.
