--- Comment #1 from Ken Thomases ken@codeweavers.com --- Interesting. Confirming.
As a workaround while I try to debug it, you can set this key in the registry:
[HKEY_CURRENT_USER\Software\Wine\Mac Driver] "Decorated"="n"
So, there's presumably a difference in messages sent between the Mac driver handling the move and user32 handling the move.
