Scene disappear in navigation

Hi,

I've wrote a simple 3d application using dxf file loader (java3d.j3d.org/utilities/loaders.html), with the mouse navigation capability.

If I try to zoom into the scene, all the object disappear and it's impossible to navigate into the scene (a 3D room).

Does anyone know how to solve this problem?
