I installed the latest 3DxSoftware but my 3D Mouse is not working within my application

Check if your application supports 3D Mice. There is a list of such application on the 3Dconnexion site.

Check the information provided by the editor of the application regarding 3D Mouse support.

Verify the 3D Mouse is enabled within your application. Some applications require specific steps to activate a 3D Mouse. Also, you may want to do a "repair" on your 3DxSoftware driver if it was installed before your applicaton.
