Use the supplied Swing 1.02 applet to create a JFrame with a
simple JPanel of buttons. The 'Load' button is resized correctly to
the width of the 'Preprocessing parameters' button.
Now drag/resize the JFrame and the 'Load' button reverts to
its minimum size despite the fact that the minimum size
has been reset to equal that of the 'Preprocessing parameters'!!

Applet generated and run under the Symantec 2.5 PDE devel
environment.
