It's not the file overwritten, it's the text field entry in X3D-Edit 
Preferences.   And when you try to launch the preference you've 
overwritten, to use view3dscene, it tries to launch "VivatyPlayer."   -- 
"Error launching external viewer: Cannot run program "VivatyPlayer" (in 
directory "/tmp"): error=2, No such file or directory"  -- Sorry for any 
confusion.  The preference entry for viewx3dscene becomes 
"SwirlX3DPlayer", which is even more confusing. On top of that, the 
view3dScene menu item in the "View Saved Scene" menu does not get enabled.

Again, the FreeWRL preference works perfectly AFAICT, so it's very

The source includes user-modifiable default installation locations for Windows Mac and Linux, so I'm happy to include any updated default values whenever possible.
