Error in console log

Receiving the following error in log file. Not sure if it impacts anything as I'm just learning FG but thought I'd bring it up.

Error:
Ruleset Warning: font: FGF initialization failed. Name (windowtitle). File (graphics/graphics_fonts.xml

This only happens when using Wood extension.

Using FG 3.07

Anyone have any ideas to this error and / or should I refrain from using Wood extension?

I have it on my list to look at. However, if you can see the window titles, then it's nothing to be concerned with.

Cheers,
