NETSCAPE AND KDE
Not to belittle the step by step, but it should mention that the fonts you added have to be added to KDE for them to be used by KDE apps.
You open Font Manager, and it will show available fonts provided by X, the new TT fonts you added should show up on this right hand list. On the left hand list you see the fonts KDE actually has avilable to it.
Now if you want to use your new TT fonts in KDE choose them on the right and hit the add button, now they will be avilable in kde apps.
The fonts that are listed as being made avilable by X should all be present in the netscape choice menu. If your still having trouble e-mail me.
