I noticed sometimes when I would change a font and click "Set as default" ... other channels wouldn't change to the font setting.
Now I know someone might point out maybe they're not set to change with default... but I tinkered with this for a bit. I made sure all windows were set to default, but if I changed the default font, I kept running into one or two windows not changing.
It's a minor thing but I am unsure how to pinpoint the problem more properly.
