I think it's my fault. I have so many fonts installed on my 12-inch PB, and I tried copying my Font Book from the PB to an external hard drive (together with other files, mostly Microsoft Word files), and then to my MBP's Applications folder. I replaced the MBP's Font Book with my PB's Font Book. Now each time I open the MBP's Font Book, it crashes upon opening. How do I restore the MBP's Font Book to factory settings? And what's the proper way of trasnferring fonts from one Mac to another? Thanks.
