JTabbedPane painting question?

I am using JTabbedPane and I am having some painting problems.  Whenever I switch tabs, there is residual painting from the previous tab.  How can I get rid of this behavior?  I have tried the following:

//Trying to fix bad painting when switching tabs...
            tabPane.addChangeListener(new ChangeListener()
            {
                public void stateChanged(ChangeEvent e)
                {
                    JComponent comp = (JComponent)tabPane.getComponentAt(tabPane.getSelectedIndex());
                    comp.paintImmediately(comp.getVisibleRect());
                }
            });

This did not correct the problem though.  Has anyone ran across this same problem before, and if so how did you correct it?

The problem you are having comes from the setOpaque() call. You should setOpaque(true) for all of your panels if you want them to paint the background.

That seemed to correct the problem I was experiencing, but now, the first time my panel with the tabs is displayed, the first tab is showing, but the tab buttons and raised border does not appear, but if I resize the app, it does appear.

package Contract;

Not knowing the details of the sub-panels:

Contracts               contractPnl;
ContractAttachments     attachmentsPnl;
ContractProfile         profilePnl;
ContractCorrespondence  correspondencePnl;
ContractCoverage        coveragePnl;
JTabbedPane             tabPane;

Nor how you are displaying the whole thing, I can only guess.
I would first try calling tabPane.invalidate() right before you setVisible(true);  That should cause the BorderLayout to re-layout the whole thing. As an alternative, you can call getSize() on the ContractSummary and then setSize( size.width+1, size.height+1 ) -- this is an old trick from the 1.0.2 days to cause the panel to re-layout after it's been shown.

If neither of these work, post the code you use to create and display the ContractSummary and I'll fix it for you.
