JRadio Buttons not appearing properly

Question

Hi.
My application has a main class that extends JFrame. It has a simple JMenuBar. Nothing else is there on this JFrame. When a JMenuItem is selected, the JFrame is set to become invisible, create an instance of another class (which extends JPanel), adds this JPanel to its center and becomes visible again.
The JPanel class has four JRadio buttons, a JTextField and a JButton. By default, the JTextField and JButton are disabled.
The problem is that when the JFrame becomes visible again after adding the JPanel, only the JTextField is visible on the screen. The JRadioButtons and JButton are not visible.
The JRadioButtons don't become visible until I move my mouse over the area where they are supposed to be and the JButton doesn't become visible until I select a JRadioButton that enables it.
How can I solve this problem. I want all the components to be displayed (enabled or disabled) when the JPanel gets added to the JFrame and the JFrame becomes visible again.
Thanks.

Hi.
I have written a simple program that does the same
thing, but it works just fine. It's no use posting
it. Here's something else I just noted. After moving
my mouse pointer over the area where the
JRadioButtons are supposed to be, they become
visible, but if I minimize and then restore, or even
maximize the JFrame, all components on the JPanel
become invisible again until I move the mouse over
them.
Could this have anything to do with the repaint not
being called properly or something? Please help.
ShakeelWell if it works fine in your short example that is good news. That means you can narrow the problem down to the differences between the short and normall example.
Slowly add each line from the normal example to the short example until the problem appears.
