Chat Font Size Bigger Than 5

[casailor]

I tried this, even font size 5 gives main chat ONLY a larger font size, the rest of the chat boxes aren't affected, they don't change font size. Is there any way to change the font size that affects all boxes. PS I had to reinstall my game, and now /chatfontsize 5 doesn't work for even the main chat. There has to be some way to change CHat boxes to the same size font.
