Hi there I have to problems with my R4 and can not find a solution to it: 1st: Chaning fonts with select does not work. Actually I think, no theme is really used. Themes are stored in /_system_/themes/themeXX 2nd: If I try to open a *.txt file and error message popups: "Can't find FONTs of eBook. Please re-install these FONTs". Using v1.11. My OS is linux; Ubuntu 7.04 Any help is very much appreciated! Thank you.
