JButton borders

With Swing's Windows look & feel, you can remove the border from a JButton by replacing it with null:

    JButton myButton = ...
    myButton.setBorder(null)`</pre>
Unfortunately this code has **no effect** in the Aqua look & feel!

Therefore whenever you remove the border from a JButton, replace it with an empty border:
<pre>`    JButton myButton = ...
    myButton.setBorder(BorderFactory.createEmptyBorder())

This is annoying because the null seems to work. It's a subtle instance of Write Once, Debug Everywhere!
