Default Font Resets Each Time X1 Starts

Hi
A small but annoying problem: The Default preview font is Arial which I have changed to 'Courier New' which persists for the rest of the session. However, when I shut down X1 and restart it resets the Font back to Arial. Grrrr!

How can I permanently change this default value?

Btw - fantastic product. I couldn't live without it now.
