If you are using the "hyphenate" option, BookDesigner has to know what fonts are installed in your EBM. This operation takes several minutes and you have to perform it only ones.
1. Find the file GFranklinet!_Default!fnt.seb. If you have installed the EBM software at its default location, you will find this file in C:\Program Files\Franklin Electronic Publishers\eBookMan Desktop Manager\Data\Contents\Franklin!_Default!fnt.seb
2. Press "font manager" button.
3. Drag&Drop the file GFranklinet!_Default!fnt.seb to "new fonts found" window (or open it using "load new font" button) and the corresponding fonts will appear in the "new fonts found" window.
4. Clicking on the font names in the window "new fonts found", choose the font suitable for you (you will see the book paragraphs preview in the "EBM hyphenation preview" window).
5. Press "add" button and the chosen font will appear in the "installed fonts" window. If you want to install more than one font, just repeat the operations 4, 5.
6. Close "EBM font manager" window and press "make book" button.
7. Load the newly created book to your EBM, run MobiPocket Reader program, load the book to it and choose the proper font.
