I try to change the SYSTEM fonts permanently. Followed this instruction:
I put the 3 system fonts in a folder on the root of the reader.
Fonts changed: tt0003m_.ttf
Changing works +- But when restarting the reader, problems arise:
-reader is booting very long
-after rebooting every note made in books, actual pages, bookmarks, ... are deleted
-interface is messed up (wrong icons, missing text). After opening a book and closing it, interface is OK. Even the new font is present.
-On rebooting once more every note etc. is deleted...
Thanks for having an idea what's wrong and helping!
