gnue connections does not save

Hello,

I am new to gnue. I tried to add a connection using "gnue connections"
I added a new record filled un the fiels and tested the connection. all ok.
Now when I try to save the configuration nothing happena dn when I try 
to change to the query mode I get a message box telling me in german

"Die Daten sind noch nicht gespeichert...."

The data is not yet saved.

Does anyone know the reason why data is not saved ?

Bye
Andreas
