Hi,

I have a strange basic problem with windowClosing() in a JFrame.

Has anybody seen this before?

Many thanks.
Bernard

/*

When I click on the "Test" button,  then the "Right" button gets the
focus border although it is disabled.
The bad side effect is that the [Alt+F4] key combination no longer
closes the frame.
If jButtonCenter.requestFocus(); is coded, then on [Alt+F4], the focus
border jumps back to jButtonRight and closing does not work either.
This is tested with JDK 1.4 under Windows 98.

What would be a clean and simple method to avoid this strange
behavior?
