Hello everyone

I encounter a weird problem: I have several JPanels (ImageObject) on a
JPanel (topPanel) inside a JScrollPane (both inside Folder) - the
ImageObjects get displayed fine - but the JCheckBox and JRadioButton
which are positioned on the ImageObject (which is a subclass of JPanel)
are not clickable. To say it right: they get the WinXP-L&F "orange
glow" when I move the mouse pointer over them - but when I click them
the do not change state. They don't fire an ItemState or
ActionPerformed event either.
Here's the code - maybe one of you Java-Gurus can see what I'm doing
wrong...

The Folder class is the container so to speak - it contains the
JScrollPane and the topPanel. ImageObjects (see below) get added to the
topPanel via the addImage() method in Folder.
The ImageObject class below contains the problematic
JCheckBox/JRadiobutton (selectedCheckBox, groupRadioButton).

Well, thanks a lot for having a look at the problem!
