#3 Check Boxes not working in group boxes

[David Botton]

Check boxes don't seem to work properly when they are created as
child controls of a group box.. Radio buttons work fine in the same
circumstance. I am writing an app which doesn't set any kind of
click handler for any of the radio buttons or check boxes; I have a
'Done' button which has a button-pushed handler which examines
the various radio buttons and check boxes and discovers their
states. The workaround is to make the check boxes children of the
main window on which the group box is created. This works, but is
awkward, as I can't move all of the check boxes at once by
putting the group box in another place, nor can I make them all
invisible at once by making the group box invisible.
