This may help; I open the piranha-gui to look & see if there was any 
error. After I closed the piranha-gui screen, Inoticed the following 
errors in /var/log/piranha/piranha-gui:

( There are 10-15 more similar error messages........ )

Is it causing the problem I am encountering? What is this error? Is it 
supposed to be there?
