Yes, the issue is still present in wine 1.4.
MYOB has done something weird by setting up these buttons as radiobuttons but displaying them as normal buttons. I can fix the problem with the attached patch, which notifies the parent window as well when the radio button is clicked.
The patch seem to play nicely with other apps, eg Word and games, but I don't know if it might have broken anything.
