--- Comment #20 from Qian Hong fracting@gmail.com 2013-09-12 04:14:21 CDT --- I found a workaround to make Fetion works on Wine: native msftedit.dll + native riched20.dll + flash plugin.
When trace the log, I found Fetion wants class RICHEDIT50W, Wine's buitlin msftedit.dll is mostly forwarded to riched20.dll, while builtin riched20.dll has registered class RICHEDIT50W, native riched20.dll may not register this class, that's why native riched20.dll is not enough to work around this bug.
