eheheh... that was the first stuff I've thought.... It works, I mean, adding
the NULL byte make app read the correct amount of bytes (so, I guess that one
is the correct behaviour) but it hangs anyways with 100% cpu as before.
So, I guess the real bug is another one, even if the null byte is (IMHO) still
needed.

I've tryed many stuffs, from a complete +rich*** log, +ole*** log, many
embedded print messages in all calls (ole has very few TRACEs, indeed....), but
I couldn't
manage to make it work. Richedit (and OLE) logs just shows that the app hangs
returning from message handling function, but I couldn't find if it's inside
Autocad (I think so...) or inside wine code.
Autocad don't run with +relay, and the usage of a BackTrace() embedded function
 ( seet devel mailing list) didn't help too much.

@Austin : the log (with many printf() messages added) is already here, the
first attachment. As you can see, it shows nothing :-(

Suppressing the \fonttbl output makes autocad work almost perfectly (there are
some other unrelated bugs in richedit code).
Native riched20 didn't help either, as already told here.

Ciao
