-
- First, NB4 (just like NB3) is a pure text mode application. It
- performs no graphics footwork, everything is managed in character/text
- mode. The foreign language font support operates by loading an
- alternate font description in video memory that your video card uses
- instead of the font description built into its ROM for text mode.
- There should be no difference in speed--it sounds as if you may be
- using some system-level software that is affecting video and keyboard
- I/O or perhaps conflicting with NB's management of those functions.
-
- There is no special graphics mode in NB4, as I say, but you *can*
- unload NB4's own fonts and palette by using the [Ctrl] + [Alt] + [Esc]
- key combination. You can later reload them with [Ctrl] + [Esc].
