WS=> You were right!  Here is the output

gvfs-mime --query inode/directory
Default application for 'inode/directory': firefox.desktop
Registered applications:
     engrampa.desktop
     firefox.desktop
     org.kde.gwenview.desktop
     caja-folder-handler.desktop
Recommended applications:
     engrampa.desktop
     firefox.desktop
     org.kde.gwenview.desktop
     caja-folder-handler.desktop

WS=> This sounds like this is my problem.  What file do I have to edit 
to correct the problem.  I will use "Xed" ( a simple text editor ) to 
make the changes.  I don't like to use emacs or other text editors 
because they are not very user friendly.

WS=> Do you have any idea on how the change was done?  I want to know so 
I can avoid doing that again.
