java application minimized mysteriously (ibm-jre-1.5.0)

Hello.

Am I the only person who have problem with java application suddenly
mysteriously minimized into task bar?

This is not always reproducible but it's easy to reproduce it:

   1. Open a java application that has a dialog (almost all java
      applications has a dialog, e.g. "File Open" dialog). My example is
      to use freemind and to edit a node value in a dialog.
   2. At the moment the dialog pops up, both the main application window
      and the dialog immediately minimized to task bar;
   3. if you click either the main window or the dialog in task bar,
      hoping to restore the windows, then the window being clicked would
      restore and immediately (after 1/10 seconds maybe) minimized again;
   4. The only think you can do is to right click the dialog in the task
      bar, select to close it, then click the main window, then it
      restores. which means, such "sudden minimize" only happen if an
      application has more than one window (e.g. a main window and a
      dialog);

I had been suffering from this problem for several years now.
environment: ibook/ppc, ibm-jre-1.5.0. Does anyone else suffer from this
problem?

Best regards
