What is it with the Font? Does it really matter? Personally I quite like the "Retro" look but I would much rather they spend their time making a version you can re-order the Macros and Favourite keys before spending time with font options.

Where has my paragraph spacing gone?

You could try this as I had a similar issue and it was nothing to do with the Sofabaton. Go into all your equipment’s settings and turn off CEC, eARC, Viera Link etc etc. I even had to stop using HDMI2 on my TV altogether as even with eARC turned off on the TV and Receiver some communication was still going on. I now have an optical cable going from TV to Receiver just in case I ever need to use the TV as a source and display.
