Comment 3 for bug 572815

There was a change in the XML code for buttons that I was unaware of, the new format for buttons is:

<?xml version="1.0" ?>
<content type="Button">
<ContentData Name="VAX" Author="Shaun Marolf" Copyright="Vaxxipooh"/>
<theme Top="0" id="HasTop">
 <Background Image="start-here.png" ImagePressed="start-here-depressed.png" ImageHover="start-here-glow.png"/>
</theme>
</content>

The new line, <Background Image="start-here.png" ImagePressed="start-here-depressed.png" ImageHover="start-here-glow.png"/> needs to be present in the XML code of the button to work correctly.
