--- Comment #3 from Rosanne DiMesio dimesio@earthlink.net --- Your summary says the problem is with "big" books, but your description says it crashes when you start Kindle for PC. Which is it?
If it is only "big" books, how "big" does a book have to be to trigger this problem? Is there a free one that demonstrates the problem that I can download to test? I'm not seeing any crashes on my system, but I also don't have any books that I would consider especially "big."
As for the fonts, if this really only happens with "big" books, that's unlikely to be the problem, but you can test it by installing winetricks corefonts. You can also try installing Kindle for PC to a 32 bit wineprefix.
