java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

A non-modal JDialog remains visible even after a call to setVisible(false).
This happens when the call to setVisible(false) is made at the time the parent
JFrame has been minimized (iconified) by the user.

/** To duplicate the bug:
 *  0. Compile and run the program below.
 *  1. Hit the "Perform Long Computation" button
 *  2. Minimize (iconify) the application.
 *  3. Wait for 5 seconds (until "computation" is over).
 *  4. Restore (de-iconify) the application window.
 *  5. The "Wait" JDialog is still visible, although
 *     a call to setVisible(false) has been made.
 *  6. This behavior didn't happen on Solaris and Linux platform
