The problem arises when I create an eps. file in quark and open it in photoshop. This error message comes up: This file uses one or more fonts which are unavailable on this machine. Rasterize anyway? When I press 'continue' the file opens with typewriter or another font instead of arial. ************ I have since added arial to the 'System folder'- which I copied from the 'System'. I followed the MacOS X book to load fonts but it doesn't make a difference.
