--- Comment #5 from Alex Villacís Lasso a_villacis@palosanto.com 2008-04-21 18:00:32 --- Created an attachment (id=12377) --> (http://bugs.winehq.org/attachment.cgi?id=12377) Accept RTF stream that does not start with {\rtf1 in 1.0 emulation
EM_SETTEXTEX has nothing to do with this bug. App streams in a RTF stream in 1.0 emulation mode, but does not prefix it with {\rtf1 header, so builtin inserts it as plain text. Patch already sent to wine-patches.
