Cripes

Thanks for the reply.
I had edited my original post with extra info while you were answering. It works fine from the command line.

I've looked up .service files and added the following in /usr/share/dbus-1/services/datable.service

[D-BUS Service]
Name=datable
Exec=/usr/bin/datable

and restarted - still no joy any suggestions gratefully recieved.

Thanks Rick
