--- Comment #15 from Rosanne DiMesio dimesio@earthlink.net 2012-02-22 06:29:06 CST --- I found a comment buried in the AppDB under Kindle 1.6.1 that says the crash on opening books is caused by missing fonts, and the workaround is to install winetricks allfonts. I have the MS fonts installed systemwide.
So, does winetricks allfonts fix it for any of you?
