Hello,

since I got no response to my problem, I leaked some litres of sweat and
found a way to circumvent the problem.
What I do now is:
    - by default the radiobuttons are made invisible
    - when the TAB contaning the radiobuttons is pressed (MousePressed event
upon JTabbedPanel - using the getSelectedIndex) method) I make the
radiobuttons visible and execute the Validate method for my instance of
CheckBocPanel
    - when any other TAB is clicked I make the radiobuttons invisible

Since I am a newbie on Java, I do not know whether this is common practice,
or is it a workaround for a bug. Perhaps anybody out there can tell me this?

Thanks,
    Arie
