The emulator is not "lighting" the buttons as described in the Install PiFace Digital Software documentation. The hardware is the PiFace Digital 2 board. Raspbian was updated/upgraded as per the directions. The hardware appears to be working. When I ran the "Reading an input" program, Python is properly reporting the state of the button.
Initially, I was getting an error saying, "QGtkStyle was unable to detect the current GTK+ theme." Thinking that perhaps the missing style was preventing the button image color change, I created a /home/pi/.gtkrc-2.0 file containing the line:
gtk-theme-name="Clearlooks"
and added the line:
export GTK2_RC_FILES="$HOME/.gtkrc-2.0"
to the /home/pi/.bashrc file. The startup error went away, but no change occurred in the application. Starting the emulator, generates a series of warning messages, but those are also displayed when I start leafpad.

Selecting the Output Control buttons does cause the PiFace to trip the relays and turn on the LEDs. The correct image version of the PiFace Digital is shown - version 2. This appears to be the only problem. Is this a bug? Or am I missing some piece of configuration? Thank you.
