Freefont error

[Kernelpanic]

Hint:  Screen 0 requires fonts to be MONOSPACED, as it doesn't work with variable-width fonts. 
Hinr2:  Screen 0 only uses ONE font for the whole screen.  When you change font on SCREEN 0, you change all the text to use that font.

Ok, now I understand how it works; I think so.    Thanks!
