Window image showing "White" (RW) edit controls what should be "Grey" (RO)

While running SIV (http://rh-software.com/) with an updating [Volumes] page the
screen does not get repainted when I send an EM_SETREADONLY to change R/W to
R/O.  I discovered I can work-a-round this by doing an InvalidateRect() on the
child window as follows:
        SendMessage( chl, EM_SETREADONLY, FALSE, 0 );
        if( mode & MODE_WINE ) InvalidateRect( chl, NULL, TRUE );
This is the case for both Set and Clear of EM_SETREADONLY.  Note that SIV is
just changing the EM_SETREADONLY property, it is not changing the text.
It would probably be less effort for me to actually change SIV to add the
work-a-round code than report the bug in Wine!, but...
