Can not start the Ruby Supervisor Screen

[Belinda Frick]

One cause could be that your printer driver is not setup correctly. The
Ruby Supervisor screen uses the Printer Driver to generate some of it's Graphs
and if the Printer driver is not installed correctly or not accessable the
program can't generate the correct screens.

Another cause: The user trying to start the Supervisor didn't log into the
computer at startup. Close all the programs and login again.
